    We report two new eclogite localities (at Kanayamadani and Shinadani) in the high-P (HP) metamorphic rocks of the Omi area in the western most region of Niigata Prefecture, Japan, which form part of the Hida Gaien Belt, and determine metamorphic conditions and pressure–temperature (P–T) paths. The metamorphic evolution of the eclogites is characterized by a tight hairpin-shaped P–T path from prograde epidote–blueschist facies to peak eclogite facies and then retrograde blueschist facies. The prograde metamorphic stage is characterized by various amphibole (winchite, barroisite, glaucophane) inclusions in garnet, whereas the peak eclogite facies assemblage is characterized by omphacite, garnet, phengite and rutile. Peak P–T conditions of the eclogites were estimated to be ~600°C and up to 2.0 GPa by conventional cation-exchange thermobarometry, Ti-in-zircon thermometry and quartz inclusion Raman barometry respectively. However, the Raman spectra of carbonaceous material thermometry of metapelites associated with the eclogites gave lower peak temperatures, possibly due to metamorphism at different conditions before being brought together during exhumation. The blueschist facies overprint following the peak of metamorphism is recognized by the abundance of glaucophane in the matrix. Zircon grains in blueschist facies metasedimentary samples from two localities adjacent to the eclogites have distinct oscillatory-zoned cores and overgrowth rims. Laser ablation inductively coupled plasma mass spectrometry U–Pb ages of the detrital cores yield a wide range between 3,200 and 400 Ma, with a peak at 600–400 Ma. In the early Palaeozoic, proto-Japan was located along the continental margin of the South China craton, providing the source of the older population of detrital zircon grains (3,200–600 Ma) deposited in the trench-fill sediments. In addition, subduction-related magmatism c. 500–400 Ma is recorded in the crust below proto-Japan, which might have been the source for the younger detrital zircon grains. The peak metamorphic age was constrained by SHRIMP dating of the overgrowth rims, yielding Tournaisian ages of 347 ± 4 Ma, suggesting subduction in the early Carboniferous. Our results provide clear constraints on the initiation of subduction, accretion and the development of an arc-trench system along the active continental margin of the South China craton and help to unravel the Palaeozoic tectonic history of proto-Japan.

    In this contribution we review the possibility of establishing the depositional age and tectonic settings of metamorphosed carbonate rocks from continental collision zones in the East African-Antarctic Orogen. The geochemical characteristics of regionally distributed meta-carbonate rocks from the Highland Complex (HC) in Sri Lanka are considered in detail and compared with similar occurrences in East Antarctica, India, Madagascar and Africa. The variations seen in the Highland Complex of Sri Lanka imply that carbonate deposition was younging from west to east, spanning apparent ages from Mesoproterozoic to Neoproterozoic. In the case of East Antarctica, such variations are within the Neoproterozoic, whereas in southern India, Madagascar and Mozambique they have a broader age range possibly from the Paleoproterozoic to Mesoproterozoic. There is also clear evidence that some carbonates were deposited in an open ocean surrounding volcanic islands in the Mesoproterozoic. Shale-normalized REE patterns have typical signatures of open ocean deposition in a passive continental margin with variable continental input in platforms nearby to island arcs. In comparison to Phanerozoic equivalents, the absence of a Ce anomaly is most significant, whereas other parameters such as (Pr/Yb)SN, (Pr/Tb)SN, and (Tb/Yb)SN were used to evaluate relative enrichments of the LREE, MREE and HREE fractions that are characteristic of ambient seawater. Pronounced La, and Y anomalies with minor Eu and Gd anomalies and correlations of REE parameters and anomalies with carbon and oxygen isotopes, 87Sr/86Sr initial ratios and εNd values are evaluated for meta-carbonate rocks in the Proterozoic collision zone. The εNd values and Sr initial ratios suggest that basins in the western Mozambique Ocean that separated the East Gondwana from West Gondwana received contributions from Archean continental crust and ambient seawater, whereas the eastern Mozambique Ocean had REE contributions from specific cratonic continents in passive margins or from continental/volcanic island arcs in active margins.

    Detailed geological mapping along with structural and geochemical analysis were carried out in the Kibbanahalli Schist Belt (KSB) of the Bababudan Group in the Western Dharwar Craton (WDC). Repeated sequences of sedimentary rocks and volcanic rocks with conformable contact relations are the major lithological association in KSB. Sedimentary structures and field relations indicate that the Bababudan Group begins with basal conglomerate composed of debris (talus) and alluvial fan deposits or fluvial deposits. Volcanic rocks preserve features of explosive volcanism in an aqueous environment. Based on the field and microstructural observations five stages of deformations (D0, D1, D2, D3, and D4) are characterized from the study area. Among these deformation events, D2 is the major regional-scale event. East dipping NW–SE trending thrust faults and F2 parallel folds that are upright and isoclinal mark the D2 event. These F2 folds are sandwiched between D2 thrust faults. D2 structures suggest the temporal evolution of a fold-and-thrust belt by inversion of an intracratonic basin. Trace element geochemical analysis of the mafic to intermediate rocks from KSB and Chitradurga Schist Belt (CSB) shows three types of patterns. Type 1 has Nb–Ta negative anomalies, Type 2 is relatively flat trend and Type 3 has Zr–Hf positive anomalies. Type 1 has slightly enriched LREE trend while relatively flat LREE trend in Type 2 and 3. HREE trend is relatively flat in all samples, except for one sample from Type 3. The geochemical variations are related to the degree of crustal contamination experienced during their eruption in connection with the intracratonic extension. A pair of thrust faults and folded sequences of volcanic, volcanoclastic and sedimentary rocks summarize the major structural association in the study area. This association is identical to an inverted failed rift structure. Geochemical evidence also points to an intracratonic mafic to intermediate volcanism. Our study thus provides a well-preserved example of Archean failed rift. We thus propose the post-3.0 Ga crustal growth throughout the Western Dharwar Craton is therefore initiated by similar failed rifting events.

    Mafic dyke swarms are one of the major geologic features that represent crustal extension and rifting episodes which result in the transfer of large volumes of mantle materials to the crust. The rapid emplacement of dykes within a short span of time helps to preserve the composition of subcontinental lithospheric mantle (SCLM) and understand its evolution over time. Here we report major and trace element geochemistry and Sr-Nd isotopic characteristics of dykes from the Tiptur area in the late Archean Western Dharwar craton of southern India. The studied mafic dykes are un-metamorphosed and preserve pristine igneous textures and mineralogy. Three different groups of dykes were identified and categorized as olivine dolerites, dolerites and REE enriched dolerites, based on the distinct petrographical and geochemical characteristics. Olivine dolerites are having a high Mg# suggesting a lower degree of fractionation and is indicative of a less evolved magma. Dolerites have comparatively lower Mg# than the olivine dolerites indicating that the former have undergone significant fractional crystallization as confirmed by the higher Ni contents. The low initial Sr isotopic ratio for olivine dolerites (87Sr/86Sr = 0.70088) with negative epsilon Nd values are suggesting a late Archean enriched subcontinental lithospheric mantle (SCLM) in the source region. The dolerites (87Sr/86Sr = 0.70132 to 0.70327) and REE enriched dolerites (87Sr/86Sr = 0.70405 to 0.70653) show signatures of a more enriched source. The evolution of SCLM from a DMM source enriched by the subduction of the mafic oceanic crust in the late Archean to a mantle enriched by continent-derived sediments towards the early Proterozoic are reflected in the dolerite and REE enriched dykes.

    The Renge Belt is a rare subduction-related metamorphic belt that contains blocks of eclogites, meta-gabbros, schists and other rocks in a serpentinite mélange that formed in the early-to-middle Paleozoic of proto-Japan. We report here a detailed geochemical and Sr–Nd isotope study of two major groups of rocks within the Omi serpentine mélange: 1. medium-grade metamorphosed blocks of meta-gabbros, and 2. high-pressure low-temperature eclogites and mafic schists. Bulk rock geochemistry of the meta-gabbros reveals that they have prominent Nb, Ta and Ti negative anomalies, suggesting an arc origin. In contrast, the eclogites, and mafic schists have trace element spider diagrams and REE patterns that resemble modern oceanic crust. The Sr–[sbnd]Nd isotopic compositions also show concomitant variations with a highly depleted source for the meta-gabbros (εNd values of +1.3 − +9.6 and Sriratios of 0.70301–0.70460) compared with a MORB/OIB-like source of the eclogites and mafic schists (εNd values of −1.94 – +4.83), although the latter have Sr isotopes variably affected by seawater interaction (Sriratios of 0.70518–0.71050). Altogether, the geochemical features suggest that the meta-gabbros were part of a magmatic arc, which developed in the Cambrian and was tectonically eroded and subducted together with oceanic crust and sediments in the Devonian–Carboniferous. The ages of detrital zircons in the pelitic schist (3200–600 Ma) suggests that the South China Craton and northeastern fringes of Gondwana were potential source regions and that the sedimentation occurred most likely in a trench. The abundant Early Paleozoic (peak around ca. 470 Ma) detrital zircons were derived from an active subduction-related arc. The protoliths of meta-gabbros are lower crustal equivalents of an infant arc, which was subducted via subduction erosion in the Devonian–Carboniferous and reached a HP metamorphic depth in the Tournasian. Our results suggest that the formation of proto-Japan was related to the initiation of intra-oceanic arc as early as Cambrian. Following tectonic erosion, the remnant mafic rocks were amalgamated with trench-fill sediments during incorporation in an accretionary complex. Subduction erosion was active where sediment supply was low and where the arc was immature. Subduction of oceanic crust was continuing to at least the middle Carboniferous, when the eclogites and blueschists were formed and later exhumed along with the meta-gabbros in serpentinite diapirs in the mid–late Paleozoic.

    To further constrain the tectonic evolution of the convergent margin of the West Mongolian segment in the Paleo–Asian Ocean, we have investigated coarse-grained kyanite metapelites associated with quartz veins in the Gobi Altai Mountains, Mongolia, where the metamorphic belt is in a thrust contact with a Paleozoic accretionary complex. The metapelites contain coarse-grained granoblastic kyanite grains that are surrounded by sillimanite (Sil-II) with moat-like andalusite (And-II). The garnet grains in the garnet-bearing kyanite metapelites contain inclusions of andalusite (And-I) in their cores and sillimanite (–Sil-I) in their mantles. Detailed textural characterization of the aluminosilicate phases indicates five distinct generations in the sequence andalusite (And-I), sillimanite (–Sil-I), kyanite (Ky), sillimanite (Sil-II), and andalusite (And-II). Thermobarometric calculations and thermodynamic modeling suggest a hairpin-shaped P–T evolution with prograde conditions starting from ~530 °C at 3.5 kbar, reaching a peak of 600 °C at 6 kbar, and then a retrogression to ~550 °C at 4 kbar. U-Pb zircon and U–Th–Pb monazite ages indicate that the multistage aluminosilicate formation has occurred during c. 260–245 Ma. The detrital zircon age distribution is essentially similar to those in the accretionary sedimentary rocks from the entire Altai Range (a sharp peak at 550–490 Ma and a broad peak at 900–700 Ma), but is characterized by more abundant Proterozoic zircon grains and an older maximum deposition age (Early Ordovician) compared with Devonian pelitic gneisses in the Mongolian Altai. These petrological and geochronological results indicate the following development of the orogen: (1) Subduction of an oceanic plate beneath a microcontinental block as early as 550 Ma, evidenced by the youngest peak of detrital zircon ages. (2) Development of the accretionary wedge and volcanic front due to maturation of the arc until c. 360 Ma. The development of the volcanic front due to the magmatism has provided abundant Paleozoic detritus to the accretionary wedge and has stemmed supply of Proterozoic detritus from the inland at the same time. (3) Burial of the youngest accretionary wedge at c. 360–350 Ma, which is not observed in the current samples. Ridge subduction has also been suggested to have occurred in this period. (4) Arc magmatism in the upper (older) part of the accretionary wedge during the late Permian that resulted in prograde high-T and low-P metamorphism (formation of And-I). (5) Burial of the heated accretionary wedge to a depth of ~20 km due to subsequent collision (formation of Sil-I and Ky) at c. 260 Ma. (6) Rapid exhumation of the buried accretionary wedge to a shallow depth by thrusting (formation of Sil-II and And-II) at c. 245 Ma. In summary, the metapelites in the Altai Range clearly preserve the evolution of both the accretion and collision events as well as their transformation processes, which are likely to be a good natural example of the Wilson cycle for a period of ~300 Myr.

    The age-unknown Hyangsanni Dolomite is distributed in the northeastern part of the Okcheon metamorphic belt in central South Korea. It has been claimed as Early to Middle Cambrian because of the misidentified Archaeocyatha fossil in the past, but the time of sedimentation has not yet been confirmed. We performed elemental and isotopic analyses for the Hyangsanni Dolomite. The REE + Y patterns of the samples of the Hyangsanni Dolomite are generally flat and Ce negative anomaly is generally negligible to the extent that it appears only weakly in some samples. Y/Ho values are in the range of 29–43, which is fairly lower than typical Y/Ho ratio of seawater, indicating the influence of terrigenous materials. REE and trace element geochemical discrimination diagrams indicate that the Hyangsanni Dolomite was deposited in a continental margin environment rather than an open ocean. We suggest that the Hyangsanni Dolomite was deposited in a rift basin connected to the ocean rather than in the passive continental margin, considering occurrence of magmatism related to continental rifting within the Okcheon metamorphic belt. Carbon and oxygen isotope analysis was performed on dolomite powders scraped off from polished surfaces unstained with Alizarin-Red-S in order to avoid the recrystallized calcite. The Hyangsanni Dolomite has δ13C(V-PDB) values between +2.9‰ and + 6.2‰, and δ18O(V-SMOW) values between +11.3‰ and + 24.5‰. These δ13C values are markedly higher than the Cambro-Ordovician values, and are consistent with the Neoproterozoic values. The minimum value of 87Sr/86Sr ratio obtained from the Hyangsanni Dolomite also refers to Neoproterozoic, not Phanerozoic. We suggest that the Hyangsanni Dolomite belongs to the sedimentary sequence of the Neoproterozoic, along with other sediments of the northeastern Okcheon metamorphic belt.

    The petrogenesis of orbicular rocks is still enigmatic because of the unique texture and variable compositions. In this study, we focus on the textural characteristics and mineral compositions from Huangling Orbicular Granodiorite (HOG), where orbicules with rhythmic growth texture and radial growth texture exist in the same outcrop. Textural and isotopic studies of zircons from different parts of the representative orbicules show three age groups of 1961 ± 19 Ma, 890 ± 6 Ma and 852 ± 6 Ma, corresponding to the ages of protolith crystallization, melt emplacement, and input of a new magma, respectively. Combined with field relationship, Ti-zircon crystallization temperature, trace element modelling and Hf isotopic data, the HOG may be derived from high-temperature contact process that involved the partial melting of granodiorites in contact and interaction with a quartz-bearing dioritic intrusion. Textural features and mineral compositions of the studied orbicules show that different textures are related to different states of crystallization. Orbicules with a rhythmic growth texture have disequilibrium crystallization zone with feldspar An contents of 34–46 and a “W”-shape pattern (forming rhythmic layers), and near-equilibrium crystallization zone with An contents of 42–44 (forming the inner part). Orbicules with a radial growth texture was crystallization in disequilibrium, as An contents show approximate linear variations of 32–44 to form radial growth layer, and with An varies 26–46 to form the inner part. Our observations support the magma quenching hypothesis, proposed as hot orbicule melts underwent rapid cooling with inward crystallization. Moreover, we firstly suggest that the amphibole-plagioclase disequilibrium crystallization could explain different textures of orbicules. Rhythmic growth texture and radial growth texture are formed at undercooling state with fast and slow cooling rates, separately. The numbers of rhythmic layers are controlled by the duration of undercooling state, while the width of each layer is controlled by the cooling rate. If excess amphibole components left in the center of orbicule melt, the “core” will be mafic. Otherwise, the “core” will be felsic.

    The Vijayan Complex (VC) of Sri Lanka is a Neoproterozoic arc terrain having no convincingly proven counterpart elsewhere in the Gondwana supercontinent. Therefore, little is known about the nature of its pre-Gondwanan ancestry. We present here new elemental and Sr-Nd isotope systematics of orthogneisses to envisage the origin and evolution of the VC. Samples with high and variable Sr-initials and negative εNd 1 14 are compatible with their derivation by melting of older rocks with a long crustal residence history. Most of the studied rocks show depleted-mantle-model ages (1.4–3.3 Ga) considerably older than the ∼1 Ga magmatic crystallization age of the VC. The rest of the samples show model ages of ∼0.9–1.1 Ga, coeval with the crystallization age of the VC, indicating separation from the mantle as juvenile inputs. Therefore, protolith sources of the majority of these rocks are mixtures of distinctive components formed much earlier than the time of predominant magmatism (∼1 Ga) in the VC. Major and trace elements and rare earth element ratios divide these samples into two categories. The “Depleted Group” represents protoliths similar to Proterozoic oceanic island basalt–like mantle materials that intensively interacted/ mixed with different proportions of melts derived from juvenile and ancient lower crust. The “Enriched Group” represents mid-ocean ridge basalt–like mantle materials subsequently interacted/mixed with variable amounts of melts derived from Archean felsic and mafic crust. Geochemical-mixing modeling with87Sr/86Sr and143Nd/144Nd confirms the involvement of above multiple source components. Thus, our findings illustrate evidence for hybridization of mantle-derived melts from various juvenile and ancient crustal components. Therefore, this first finding of Paleoproterozoic to early Archean–aged components within the VC provides new insights to elucidate its pre-Gondwanan geodynamic setting, revising the previous understanding of it as an “exotic terrain” to Gondwana with only largely juvenile Neoproterozoic materials.

    We report the results of kinetic experiments of graphitization at various pressures (0.5–8.0 GPa) and durations (1 s to 24 h) at 1200 °C. The natural carbonaceous material in sedimentary rocks from the Shimanto accretionary complex and the Hidaka metamorphic belt, Japan, underwent systematic changes in crystallinity and morphology with increasing pressure. To assess the pressure dependence of graphitization, we adopted three approaches to formulating the graphitization kinetics using a power law rate model, a Johnson–Mehl–Avrami–Kolmogorov model, and a superposition method. Activation volumes of − 21.7 ± 3.0 to − 45.7 ± 4.5 cm3 mol−1 and − 0.7 ± 0.2 to − 16.8 ± 1.8 cm3 mol−1 were obtained for pressures from 0.5 to 2.0 GPa and 2.0 to 8.0 GPa, respectively. Such large negative activation volumes might arise from structural modification and compression in the primary carbonaceous material. We applied the experimental data to the Arrhenius-type equation of graphitization, extrapolated to geological P–T–t conditions. Our model predicts that carbonaceous material undergoing metamorphism for ~ 10 Myr at pressures of 0.5–3.0 GPa will begin to crystallize at around 350–420 °C and transform fully to ordered graphite at around 450–600 °C, depending on the peak pressure. Thus, natural graphitization might proceed much more rapidly than previously estimated, owing to the large negative activation volumes for the reaction rate. This indicates that subducted carbonaceous materials will completely convert to fully ordered graphite by rapid recrystallization and metamorphic devolatilization before reaching sub-arc depths (< 100 km).

    Neoarchean orthogneiss, dated at 2629 ± 9 Ma by SIMS zircon U-Pb, has been discovered in the Rusizian terrane of the Western Domain of the Karagwe Ankole Belt, Rwanda, redefining the NW margin of the Tanzania Craton. Metamorphism of the orthogneiss at 1959 ± 4 Ma was associated with Paleoproterozoic granitic arc magmatism in the Rusizian terrane over the period ca. 2000–1840 Ma. The major and trace element composition of the peraluminous, calc-alkalic orthogneiss is consistent with magmatism in an arc setting at an active continental margin. Its Nd depleted mantle model age of ca. 2800 Ma is consistent with derivation by partial melting and reworking of older crust at the NW margin of the Tanzania Craton. The Paleoproterozoic thermal event was related to the accretional collision between the Congo and Tanzania Cratons during the assembly of the Nuna supercontinent. Future tectonic modelling of the Karagwe Ankole Belt must take into account the presence of Archean basement beneath the Western Domain.

    Sri Lanka is endowed with high purity vein graphite deposits with extensive mineralization in the tectonically weakened zones of the basement high-grade rocks. Distinctly different crystal shapes of graphite are found even within a single vein and it is controversial in interpreting prevailed fluid activities and crystallization process to form such a variation. Therefore, this study was carried out to interpret the origin of vein graphite using geochemistry, crystal-morphology, and structure of the crystals. Sampling was conducted on four different depths at the Kahatagaha-Kolongaha mine, Sri Lanka. Characterizations of graphite were carried out by micro-Raman spectroscopy, X-ray diffraction spectroscopy, scanning electron microscopy, and inductive couple plasma mass spectroscopy. The results indicate that the genesis of the vein graphite is related to a single phase of fluid activity and the fluid was mostly pure with possible trace impurities. Further, it was revealed that the thickness of the veins, interaction with host rocks and mobility of the impurity elements have influenced the formation of different morphologies of graphite in a single vein.

    Mafic dyke swarms are abundantly distributed in the Archean Dharwar craton. Previous studies have focused mainly on the major mafic dyke swarms in EDC; however, those in the WDC are yet to be studied in detail. Here we present preliminary geochemical data for the dykes in the Tiptur area, WDC and compare them with the dyke swarms in the EDC. Petrological studies indicate that the dykes in the Tiptur area fall into two distinct groups. The NW–SE trending dolerite dykes are unaltered, with characteristic ophitic textures and are geochemically comparable to 2.3 Ga EDC dykes. In contrast, the NE–SW trending meta-doleritic dykes showed high degree of alteration. The difference in petrography, major, trace and rare earth element geochemistry between the dolerites and meta-dolerites lead to a preliminary inference that these two suits of rocks might not be co-genetic. Meta-dolerites have not been reported from the EDC and it is possible to assume that they are a part of an earlier event, restricted in WDC, that might have emplaced prior to the amalgamation of WDC and EDC. In a global perspective, we compare our results with those reported in Archean cratons during late Archean to early Proterozoic around the world to constrain similarities that can lead to understanding the global scale magmatic activity and to aid in correlations between cratons.

    The redox state of pseudotachylyte provides valuable information on the physicochemical properties related to fluid activity during paleoseismicity. In this study, we evaluate the behavior of fluids in pseudotachylytes using fluid buffering minerals such as graphite and other secondary minerals. Two types of pseudotachylyte were identified in the Hidaka metamorphic belt, Hokkaido, Japan; Pst I and Pst II. Pst I is composed of pyrrhotite and K-feldspar generated by the breakdown of phyllosilicates, whereas Pst II includes recrystallized biotite microlites, K-feldspar, and plagioclase due to the breakdown of quartz and feldspars, as well as phyllosilicates. The selective frictional melting of phyllosilicates is indicated by significant changes in the concentrations of large ion lithophile elements (e.g., Ba, Sr, Rb, Cs, B, and K). In addition, the graphite associated with titanite and hydroxyapatite is often distributed within the Pst II matrix. The graphite exhibits different crystallinity, morphology, and higher carbon stable isotopic compositions (δ13C = −21.9 ± 2.3‰ n = 16), when compared with metamorphic graphite extracted from the protolith (δ13C = −25.1 ± 0.8‰ n = 15), cataclasite, ultracataclasite, and Pst I (δ13C = −25.2 ± 0.8‰ n = 15). The microstructure and geochemical signatures in both pseudotachylytes are controlled by dehydration–redox reaction of phyllosilicates coexisting with sulfide minerals and graphite. In particular, the formation of 13C enriched graphite in the Pst II can be deduced by co-precipitation of fluid-deposited graphite with hydrous minerals from H2O-CH4 fluids and/or degassing of H2O-CH4 fluids from residual graphite. Our data demonstrated that the carbonic fluids of a reducing nature could be produced, and then dissolved into the pseudotachylyte melt by frictional melting of metasedimentary rocks. The production of carbonic fluids by coseismic slip may be an overlooked process in the remobilization of refractory graphite locked in the crust.

    We report here new experimental kinetic data on the structural evolution of carbonaceous material (CM) to graphite during heating at various temperatures (1000 to 1450 degrees C) for various durations (10 min to 115 h) under a pressure of 1 GPa. Natural CMs extracted from sedimentary rocks in the Shimanto accretionary complex and the Hidaka metamorphic belt of Japan transformed in morphology and crystallinity with increasing temperature and annealing duration to become fully ordered graphite (d(002) spacing similar to 3.36 angstrom). Transmission electron microscopy showed that both samples have undergone microstructural evolution from amorphous carbon to platy graphitic carbon. These changes match the evolution of the samples' X-ray diffraction (XRD) patterns and micro-Raman spectra. The time temperature relations of crystal parameters obtained by XRD and micro-Raman spectroscopy demonstrated a sigmoidal transformation curve from an amorphous to a graphitic structure, suggesting complexity of these successive and/or parallel chemical reactions are responsible for graphitization. To assess these complex chemical processes, we adopted three different approaches for formulating the graphitization kinetics using a power rate model, a Johnson-Mehl-Avrami (JMA) model and a superposition method. Irrespective of the models employed, the effective activation energies were estimated to lie between 259 and 339 kJ/mol, which are much lower than those reported previously for graphitization. Summarizing the previous studies and our results between 0.1 and 1000 MPa, we found that the effective activation energies systematically decrease as a function of pressure. Based on the experimental results in this study, the sigmoid functions obtained from the time temperature relations can be extrapolated to low-temperature conditions at 1 GPa. Our kinetic model using unit-cell height c predicts that CM undergoing metamorphism for about 1 m.y. will begin to crystallize at similar to 410 degrees C, and will transform to fully ordered graphite at over similar to 520 degrees C. Thus, natural graphitization undergoes a much faster transformation than reported in previous studies at 1 atm and could be explored in laboratory experiments using natural precursor materials under pressure conditions and time spans that reflect natural conditions in the Earth's crust.

    Earth's tectonic and climatic systems may have changed fundamentally before the Great Oxidation Event (GOE) at about 2.3 Ga. Sulfur Mass Independent Fractionation (S-MIF) has demonstrated that Earth's atmosphere was virtually oxygen-free before the GOE. During 3.0 to 2.4 Ga, the change in Δ33S and Δ36S signals may reflect the perturbation of atmospheric chemistry, though the mechanisms of the change are uncertain. Here, we reported multiple sulfur isotopic studies of Archean volcano-sedimentary sequences of the Dharwar Supergroup, distributed in the Chitradurga Schist Belt (CSB), Southern India. New field mapping and zircon U–Pb dating allows us to reconstruct detailed lithostratigraphy of the Dharwar Supergroup. The lower unit consists of post-3.0 Ga conglomerate, stromatolitic carbonate, siliciclastics with diamictite, chert/BIF and pillowed basalt in ascending order, all of which are older than the 2676 Ma dacite dyke that had intruded into the lower unit. The upper unit unconformably overlies the pillow basalts at the top of the lower unit, and consists of conglomerate/sandstone with ∼2600 Ma detrital zircons, komatiitic basalt, BIF and siliciclastic sequence with mafic volcanics. Sulfur isotope analysis of extracted sulfides shows MIF signals (ΔS33>+1‰) with clear ΔS33–ΔS36 correlations. The lower group of the Dharwar Supergroup shows a ΔS36/ΔS33 slope of −1.48, the middle group shows −1.16 and −1.07, and the upper group shows −0.94. Reassessment of all the Archean S-MIF records from sedimentary rocks indicates that the ΔS36/ΔS33 slope systematically changed during the Archean period. The observed trend in the Indian section is similar to those of its Pilbara–Kaapvaal equivalents, thus it could reflect a global atmospheric signature. Moreover, the isotopic trend seems to correlate with mid-Archean glaciation. Thus, the ΔS36/ΔS33 slope could be a useful tracer for atmospheric chemistry and its link with climate change before the GOE.

    Komatiites near Kapili village, located in Palaeo-Mesoachean Gorumahishani-Badampahar greenstone belt of Singhbhum Craton, Eastern India preserve excellent igneous textures and exhibit co-association of Al-depleted (ADK) and Al-undepleted komatiites (AUK). The Kapili komatiites exhibit repeated spinifex textured flows (cooling units) overlying massive cumulate zone. The basal cumulate part of Kapili komatiite is chemically similar to ADK which is characterized by subchondritic Al2O3/TiO2 (9.38–10.5) and HREE depleted nature (average (Gd/Yb)PM ∼ 1.35) elucidating presence of majorite in residuum whereas compound upper spinifex lava typically display superchondritic Al2O3/TiO2 (∼22–28.5) and HREE enriched nature (average (Gd/Yb)PM ∼ 0.81) demonstrating majorite free residuum. Calculated primary magma compositions of Kapili ADK and AUK reveal that generation of primary liquid of Kapili ADK or basal cumulate took place at greater depth (>300 km) or at higher pressure (∼9 GPa) at around 30% melting of source in contrast with primary liquid of AUK (spinifex lava), which was generated at shallower depth (∼150 km) or at lower pressure (∼6 GPa) beyond majorite stability and at higher degree of melting (∼30–40%). ‘Hump-shaped’ pattern of primitive mantle (PM) normalized REE spectra of Kapili ADKs and their primary liquid is caused by depletion of both LREE and HREE with respect to MREEs. Depletion in LREE and HREE is explained by depletion of source prior melting and sequestration of HREE in residual majorite respectively. However, Kapili AUK or spinifex lava samples show flat, near primitive mantle (REE/PM ∼ 1) pattern exclusive of any significant depletion and implying higher degree of melting (between 30 and 40%) of a PM like source. Sm-Nd isotopic studies of Kapili ADK and AUK reveal that they both were derived from a mantle source with long term depletion (εNd ∼ +2 to +4). Except differences in LREE/HREE ratio featured due to differences in melting conditions, similarity in overall immobile HREE and high field strength element (HFSE) concentrations of both the types and their corresponding primary magmas suggest a single plume source rather than multiple sources, whose composition was closer to primitive mantle and eventually segregated chemically different komatiitic melts (Al-depleted and undepleted) at different depths. Whole rock Th/Yb, Th/Nb, Zr/Nb, Nb/Y, (La/Nb)PM ratios of both Kapili AUK and AUKs are comparable to oceanic island basalt (OIB) and mid oceanic ridge basalt (MORB) similar to typical greenstone belt volcanics from oceanic provenance. In addition, presence of copious pillow basalt and oceanic chert associated with komatiites, absence of negative δNb values recommend emplacement of komatiitic lava in oceanic rather than continental or arc setting.

    Carbon, the fourth most abundant element in the solar system, is believed to be an important light element constituent in the Earth’s core. The high carbon content of carbonaceous chondrites (3.2 wt.%) compared to bulk earth estimates, the presence of graphite/diamond and metal carbides in Iron meteorites, the high solubility of carbon into iron melts in the Fe-C system, all suggests the plausible presence of carbon in the Earth’s core. However, the distribution of carbon isotopes in the core and deep mantle remains elusive. Newly reported experimental data and theoretical estimates on equilibrium carbon isotope fractionation between graphite/diamond and carbide phases suggests that iron carbide melt will preferentially gather C than C. These results are consistent with the carbon isotope distribution between graphite and cohenite (Fe C) observed in iron meteorites. The temperature dependent fractionation of carbon isotopes between carbide phases and elemental carbon can be an effective mechanism that might have created a C-enriched core. If the Earth’s core is a large reservoir of C-enriched carbon, then it can result in large perturbations in surface carbon cycle caused by the flux of isotopically lighter carbon from the core-mantle boundary. 12 13 12 12 3

    We report newly obtained U-Pb SHRIMP ages of detrital zircons from metagreywackes in the Hiriyur Formation (Chitradurga Group, Dharwar Supergroup) from the central eastern part of the Chitradurga greenstone belt. U-Pb analyses yield three major Neoarchean age populations ranging from 2.70–2.54 Ga with some minor age population of Mesoarchean. The maximum age of deposition is constrained by the youngest detrital zircon population at 2546 Ma. This is the first report of the occurrence of supracrustal rocks less than 2.58 Ga in the central part of Chitradurga greenstone belt. Close evaluation of detrital ages with the published ages of surrounding igneous rocks suggest that the youngest detrital zircons might be derived from rocks of the Eastern Dharwar craton and the inferred docking of the western and eastern Dharwar cratons happened prior to the deposition of the Hiriyur Formation. The Chitradurga shear zone, dividing the Dharwar craton into western and eastern blocks, probably developed after the deposition. Furthermore, the lower intercept is interpreted as evidence for the Pan-African overprints in the study area.

    Chemostratigraphy or chemical stratigraphy deals with the correlation of sedimentary strata based on systematic variation of a particular chemical composition with time in the history of the Earth. In particular, this method is widely used in decoding the temporal variations seen in marine sediments that are deposited uninterruptedly in deep sea or in shallow marine carbonate depositional environments. In this review, the application of strontium and carbon isotope based chemostratigraphy in marine carbonate sediments is discussed. Irrespective of post depositional geological events such as metamorphism or tectonic displacements to form Mountain chains during continental collision, chemostratigraphy helps in determining the apparent depositional ages of sedimentary rocks in the Precambrian time, where biostratigraphy is not applicable. Although carbonate rocks are vulnerable to post depositional alterations, a systematic geochemical screening can guide in identifying the best chemically preserved carbonate rocks. A novel method of using Mn/Sr ratios for determining the best estimate of strontium initial ratio for carbonate rocks is presented, on the basis of a worked example of metamorphosed carbonate rocks from the Sor Rondane Mountains in the Dronning 'Maud Land, East Antarctica. The future potential of chemostratigraphy in decoding the early history of the Earth is also discussed.

    We report newly obtained U-Pb SHRIMP ages of zircons from the granitoids in the vicinity of Chitradurga shear zone of Dharwar craton, South India. The analyses yielded two different ages, an older age of ca. 3300 Ma and younger ages of similar to 2600-2650 Ma, those suggest two major igneous activities in the study area. The former activity contemporaneous with the formation of Mesoarchean (similar to 3.3 Ga) basement rocks (i.e., Peninsular Gneiss) and the latter reflects the Neoarchean (similar to 2.6 Ga) regional plutonic activity in the Western Dharwar craton. Field and petrographic observations suggest that the intensity of deformation is high at the boundary between amphibolites and granitoids. Our new age dates imply that the formation of Chitradurga shear zone postdated the magmatic activity in the study area and the deformation structures possibly related to the development of Chitradurga shear zone. The area on either sides of the boundary between Eastern and Western Dharwar cratons experienced a Neoproterozoic event between 700-600 Ma indicated by prominent SHRIMP lower intercepts.

    The whole-rock Hf, Sr and Nd isotope data of five high-Fe-Ti eclogites, nine high-Al edogites, and a garnetite from the Sulu ultrahigh pressure (UHF) metamorphic terrane at eastern China were analyzed to resolve the causes for the decoupling of the Lu-Hf, Sm-Nd, and Rb-Sr isotope systems in these UHP rocks and to infer their protolith characteristics. Seven of the nine high-Al eclogites define an Rb-87/Sr-86-Sr-87/Sr-86 errorchron age of 192 +/- 43 Ma (MSWD = 2.8), which is within the time span of retrograde metamorphism despite the large uncertainty. The high-Fe-Ti eclogites and garnetite, however, have low Rb-87/Sr-86 ratios of <0.031 with scattered Sr-87/Sr-86 ratios of 0.7042-0.7058. Accordingly, it is inferred that the Rb-Sr isotope system in the samples reflects the effects of processes postdating the UHP metamorphism. Despite having different constituent mineral assemblages and whole rock geochemistry, the samples, however, define a Sm-147/Nd-144-Nd-143/Nd-144 errorchron age of 232 +/- 36 Ma (MSWD = 4.6). Although the uncertainty of +/-36 Ma implies incomplete Nd isotope equilibrium among the samples, the large overlap between this errorchron age span and the mineral isochron ages of 245-210 Ma for the UHP metamorphism indicates the control of peak metamorphism on the Sm-Nd isotope system. The incomplete Nd isotope re-equilibration was accompanied by metamorphic modification on the Sm/Nd ratios as indicated by the U-shaped LREE patterns. The initial epsilon(Nd)(780) values of the protolith rocks calculated from the Sm/Nd ratios of the samples deviate from the igneous initial epsilon(Nd)(t)-epsilon(Hf)(t) trend to significantly lower values, consistent with the metamorphic increase in the Sm/Nd ratios. In contrast, the Lu/Hf ratios are generally within the range for basalts and do not vary systematically with the Hf-176/Hf-177 ratios. The protolith epsilon(Hf)(780) values calculated from the Lu/Hf ratios of the samples are nearly identical to the initial epsilon(Hf)(t) values of the -780 Ma magmatic zircon cores from the Yangtze craton, suggesting the dominance of protolith characteristics on the Lu-Hf isotope system, Being controlled by different processes, the Rb-Sr, Sm-Nd, and Lu-Hf isotope systems of the investigated samples are therefore decoupled. The epsilon(Nd)(220)-epsilon(Hf)(220) compositions of the samples deviate from the epsilon(Nd)(t)-epsilon(Hf)(t) trend of intraplate lavas to high epsilon(Hf)(220) at a given epsilon(Nd)(220) and are within the arc lava field. The protolith epsilon(Nd)(780)-epsilon(Hf)(780) compositions calculated from metamorphic initials using igneous Sm/Nd and Lu/Hf ratios show a similar distribution pattern, strengthening the arc affinity of the eclogites. These arc signatures together with the felsic-mafic bimodal geochemical features of the UHF rocks from the Sulu terrane are explained as the characteristics of protoliths generated by backarc rifting.

    We report here on two distinct processes of deformation affecting graphite in fault zones of the Hidaka metamorphic belt, Hokkaido, Japan. One process involves the micrometer-scale delamination (NMD) in the stacking of graphite, and the other is the nanometer-scale delamination (MMD) in the stacking plus pulverization (P) of carbon sheets to less than 10 nm. Graphite in mylonites mainly glide along the (002) planes, and they exhibit layer separation, kink banding, and bending structures produced by MMD processes, whereas NMD + P processes induce a significant size reduction and amorphization of the graphitic structures in cataclasites, ultracataclasites, and pseudotachylytes. The strain-induced amorphization of graphite, as inferred from XRD and micro-Raman spectroscopy, corresponds well with nano-to micro-scale deformation structures observed under the HRTEM, suggesting a systematic increase of edge planes by interlayer delamination and pulverization of carbon sheets. In addition, the carbon isotopic compositions of the graphite in fault rocks have negative delta C-13 signatures, indicating a sedimentary organic origin; such graphite has a tendency to accumulate within the shear bands. Our data suggest that the graphitic structures record information on both the peak metamorphic temperatures and the deformation processes, and they show the progressive amorphization with increasing brittle deformation.

    Carbon isotope fractionation between graphite and carbonated silicate melt was determined at 5 GPa and in the temperature range between 1400 and 1900 degrees C. High pressure experiments were carried out in the carbon-saturated model harzbergite system (Enstatite-Magnesite-Olivine-Graphite), where carbonated silicate melt and graphite were the two stable carbon-bearing phases in the run products. Carbonated silicate melting resulted in an isotopic fractionation between graphite and carbon in the silicate melt, where the carbon in the melt is C-13 enriched than co-existing graphite. 13C enrichment in carbonate melt when compared to graphite was further confirmed in experiments where redox melting between olivine and graphite produced carbonate melt as well as carbonate reduction experiments to form graphite. Although a quantitative estimate of fractionation between carbonate melt and graphite could not be obtained, our results indicate that mantle melting in the presence of graphite can result in progressive C-13 carbon isotope enrichment in carbonate melt and depletion in graphite, which can be an alternate explanation for the carbon isotopic heterogeneity observed in the mantle derived carbon.

    Here we report on the unexpected occurrence of felsic (granitic) inclusions with quench textures such as spherulite and dendrite (hereafter referred to as "felsite inclusions"), similar to some volcanic rocks, within garnet in presumably "slowly cooled" lower-crustal granulites of various geologic ages ranging from Early Proterozoic to Middle Paleozoic and wide global distribution (the Limpopo Belt, the Grenville Province, the Liltzow-Holm Complex of East Antarctica, the Highland Complex of Sri Lanka, and the southern Bohemian Massif). The well-preserved textures of felsite inclusions are indicative of melts formed by anatexis during high-pressure and high-temperature metamorphism, crystallization under far-from-equilibrium conditions (at >50 degrees C undercooling) and subsequent rapid cooling. The occurrence of felsite inclusions in granulites in restricted tectonostratigraphic zones in Sri Lanka, among other examples, may be the first geologic evidence for fast exhumation of lower-crustal rocks to andalusite-stable upper-crustal conditions by channel flow in a continental collision orogen. We hypothesize that granulites ascend episodically along discrete high-strain zones and cool as fast as some felsic magmas. This conclusion sheds new light on the debate regarding the deep crustal processes and necessitates changes to fundamental beliefs about exhumation rates based on rates of plate convergence (1-10 cm/year).

    Several schools of thoughts exist on how and when exactly did the final assembly of East Gondwana occurred and this topic has been discussed over and again in the past few decades. Here we review the present status of our understanding of Neoproterozoic to Cambrian tectonic evolution of the southern sector of East Gondwana and by assembling this special issue we present some of the key elements of new structural, geological and geochronological information obtained from the inland Sol. Rondane Mountains in the Dronning Maud Land and surrounding regions. Altogether fifteen contributions are included in this special issue, most off which are exploring whether the Neoproterozoic orogens of East African Antarctic orogen and the late Kuunga orogens have affected the same geological entity. The results presented suggest the importance of Sor Rondane Mountains in understanding the tectonics of the final amalgamation of East Gondwana. (C) 2013 Elsevier B.V. All rights reserved.

    We report petrologic, geochemical, fluid inclusion and stable isotopic data from an unusual spinel dunite occurring within metasedimentary units of the Late Neoproterozoic-Cambrian accretionary belt in the southernmost part of the Southern Granulite Terrain in India. The volatile-rich dunite is mainly composed of cumulus olivine with intercumulus ilmenite, phlogopite, spinel, graphite, Ni-bearing pyrrhotite and calcite. The olivine is Mg-rich (Fo~96) and unusually poor in Ni. Spinel, even though a minor component, is Mg-Al type (Mg#~0.92) and is depleted in Cr (Cr#&lt
    0.01). Phlogopite is highly magnesian (Mg# around 0.95-0.97) with high K/(K+Na) ratios of 0.93-1.00 similar to phlogopite reported from mantle-derived peridotites. Ilmenite is dominantly geikielite with Mg# ranging from 0.56 to 0.62. The calcite in this rock exhibits LREE-enriched nature with a pronounced negative Eu anomaly. Carbon stable isotope analyses on the calcite and graphite from the dunite yielded δ13C compositions comparable with mantle values. Raman peaks of matrix and inclusion graphites show highly crystalline character. The data reported in this study suggest formation of the spinel dunite from an Mg-rich melt enriched in C-O-H-S volatiles with low Ni and Cr. The silica activity appears to have been too low for the crystallization of plagioclase, pyroxenes and amphiboles. The formation of such a melt depleted in Cr, Ni and Fe suggests an early removal of Fe-Ni sulfide and Cr-rich spinel resulting in the depletion of Cr, Fe and Ni and enrichment of Mg and Al in the residual melts from which the high-Mg olivine and Mg-Al spinel cyrstallized. Fe and Ni partitioned to sulfide phase rather than olivine in shallow upper mantle/deep lower crustal levels under high sulfur fugacity. The spinel dunite of present study, together with similar ultramafic cumulate rocks occurring as dismembered units in other localities of the Neoproterozoic-Cambrian accretionary belt in southern India probably represents partial melting under the presence of volatiles in a mantle wedge within a suprasubduction setting. © 2012 Elsevier B.V.

    Archaean metasedimentary sequences of the Chitradurga Schist Belt in Western Dharwar Craton were reassessed in terms of their protoliths, potential timing of deposition and metamorphic events along with metamorphic conditions. Existing geological and stratigraphic constraints and our field observations suggest that the oldest supracrustal sequence of the Sargur Group, which occurs as enclaves in Peninsular Gneiss, is overlain by the Dharwar Supergroup consisting of lower Bababudan and upper Chitradurga Groups. In the Chitradurga Schist Belt, the metamorphic conditions of each stratigraphic unit are distinct, with most prominent difference observed in the Chitradurga Group. The lower unit of this group are metamorphosed under biotite-muscovite grade, whereas the upper unit at chlorite-muscovite grade. Detrital zircon U-Pb dates obtained by ion microprobe analyses suggest 3.14. Ga and 3.22-2.92. Ga for the youngest protolith's magmatic ages, which constrain the oldest age limit of deposition of Bababudan Group and Lower Unit of Chitradurga Group, respectively. The depositional age of Upper Unit of Chitradurga Schist Belt can be bracketed by 2.68. Ga magmatic zircon ages from meta-rhyolite and 2.63. Ga magmatic detrital zircon age of the overlying sandstone that are significantly younger than the Lower Unit. Monazite U-Th-Pb ages are similar for both Lower and Upper Units of the Chitradurga Group (∼c. 2.4. Ga) but are significantly younger than those of the underlying Bababudan and Sargur Groups (∼c. 3.1. Ga). Combined zircon and monazite data imply that the continuous or composite Mesoarchaean-Neoarchaean supracrustal sequences of the Chitradurga Group are metamorphosed together at the latest Archaean-early Proterozoic. These regional metamorphic ages are not detected in the underlying Bababudan and Sargur Groups, as well as the basement Peninsular Gneiss. Contrasting depositional and metamorphic history in coherent Mesoarchaean and Neoarchaean strata in the Chitradurga Schist Belt have important implications for the comparison with the well-established sedimentary sequences of similar ages in the Pilbara and Kaapvaal cratons. The protolith and metamorphic ages of the Dharwar Supergroup, when compared with available similar information from the surrounding Archaean cratons in India, Madagascar, and East Antarctica, testify the probable Archaean connection, and give clues to the formation of deep to shallow Archaean crust. © 2012 Elsevier B.V.

    The Central Asian Orogenic Belt consists of various terranes amalgamated in several periods from the Late Pre-cambrian/Early Paleozoic to the Late Mesozoic. Mongolia is situated in the center of this belt. Foliated garnet granite (Grt metagranite) and andalusite-bearing massive leucogranite (Leucogranite) are exposed in the Hanhohiyn region of northwest Mongolia. The results of monazite Th-U-Pb dating of the Grt metagranite and Leucogranite give ages of 508 +/- 10 Ma and 496 +/- 4 Ma, respectively. Cambrian granite with an age of similar to 500 Ma is also reported from the south-central part of Mongolia. Combined with previously published age data of metamorphic and intrusive rocks, these results show that the Cambrian orogenic belt spans over 800 km, from the northwest to the south-central part of Mongolia.

    Reconstructions of Gondwana place Dronning Maud Land, Antarctica (DML) adjacent to N. Mozambique prior to fragmentation. The Monapo Complex outlier klippen overlying the Nampula Terrane in N. Mozambique has been correlated with rocks in eastern and central DML. Metamorphic assemblages and P-T conditions from the two areas are compared as well the timing of metamorphism. Granulite grade assemblages preserved in the Monapo Complex suggest P-T conditions of similar to 90 degrees C and &gt;10 kb. Textures vary with reactions typical of isothermal decompression, isobaric cooling and hydration being recognized but also include equilibrium assemblages. P-T estimates from four samples suggest initial inversion of high pressure assemblages from at least similar to 10 kb and similar to 900 degrees C to mid-crustal levels where near isobaric cooling and hydration at between similar to 4-7 kb and 550-700 degrees C is recognized. Granulite grade assemblages from Balchenfjella in eastern Sor Rondane, DML suggest initial P-T conditions of similar to 900 degrees C and &gt;10 kb. Textures vary with reactions typical of decompression, cooling and hydration being recognized but also include equilibrium assemblages. P-T estimates from four samples suggest initial inversion of high pressure assemblages from at least similar to 10 kb and similar to 900 degrees C to mid-crustal levels where retrogression at between similar to 6-7 kb and 600-700 degrees C is recognized.
    SHRIMP zircon data from six samples from eastern Sor Rondane show episodic zircon growth over a period from similar to 630 Ma to similar to 530 Ma with five metamorphic pulses being defined. Undeformed granitic intrusions with ages of similar to 550 Ma intrude Sor Rondane. SHRIMP zircon data from samples from alkaline intrusions and mafic granulites in the Monapo Complex yield crystallization and metamorphic ages of similar to 635 Ma and 570-590 Ma respectively. The complex is intruded by granitic veins with ages of similar to 550 Ma.
    The similarities in metamorphic mineral assemblages, P-T estimates and zircon geochronology data indicate a common geological history between Sor Rondane and the Monapo Complex of northern Mozambique. This common history is interpreted to result from both areas being part of a mega-nappe structure which was emplaced in a transpressional setting involving collision between N. Gondwana (comprising rocks of the East African Orogeny) and south Gondwana (comprising the Nampula Terrane of northern Mozambique and the Maud Province of western Dronning Maud Land) along the Damara-Zambesi-Lurio-CDML collision boundary.
    Other erosional remnants of this nappe include the Mugeba Complex in northern Mozambique, the Kataragama klippe in Sri Lanka, the Urungwe klippe in Zimbabwe, the Masosa Suite and Mavhuradohna Complex in western Mozambique and NE Zimbabwe. (C) 2012 Elsevier B.V. All rights reserved.

    Chromium-rich calc-silicate rocks in the Archaean Bandihalli supracrustal belt in the Dharwar Craton, India, show a characteristic mineral assemblage that includes euhedral and anhedral (resorbed) green garnet associated with chromite, in addition to diopside, quartz, clinozoisite and calcite. Two distinct types of green garnets and a brown variety were identified in the calc-silicate rocks. These garnets show complex chemical compositional variations that range between the endmembers of uvarovite, grossular, and spessartine. Chromite grains in the matrix are euhedral or subhedral, whereas inclusions in garnet are rounded or amoeboid in shape. The two textural varieties of chromite from Bandihalli are separated by a compositional gap. Furthermore, chromites from the study area have high Cr# (0.80-0.97) and low Mg# (0.01-0.04), which is similar to the chromite in serpentinites and are in contrast with chromite compositions reported from igneous rocks. Therefore, the chromite in the calc-silicate rocks may have been derived from serpentinized ultramafic rocks. Textural and compositional data presented here provide evidence for chemical changes of the primary chromite with increasing metamorphic grade, presumably associated with primary hydrothermal alteration that resulted in serpentinization and carbonation of the ultramafic protolith. Therefore, Cr-rich calc-silicate rocks can be considered as products of metamorphosed carbonated and serpentinized mafic or ultramafic igneous rocks.

    Four different varieties of charnockitic rocks, with different modes of formation, from the Mesoproterozoic Natal belt are described and new C isotope data presented. Excellent coastal exposures in a number of quarries and river sections make this part of the Natal belt a good location for observing charnockitic field relationships. Whereas there has been much debate on genesis of charnockites and the use of the term charnockite, it is generally recognized that the stabilization of orthopyroxene relative to biotite in granitoid rocks is a function of low aH 2O (± high CO 2), high temperature, and composition (especially Fe/(Fe +Mg)). From the Natal belt exposures, it is evident that syn-emplacement, magmatic crystallization of charnockite can arise from mantle-derived differentiated melts that are inherently hot and dry (as in the Oribi Gorge granites and Munster enderbite), as well as from wet granitic melts that have been affected through interaction with dry country rock to produce localized charnockitic marginal facies in plutons (as in the Portobello Granite). Two varieties of post-emplacement sub-solidus charnockites are also evident. These include charnockitic aureoles developed in leucocratic, biotite, garnet granite adjacent to cross-cutting enderbitic veins that are attributed to metamorphic-metasomatic processes (as in the Nicholson's Point granite, a part of the Margate Granite Suite), as well as nebulous, patchy charnockitic veins in the Margate Granite that are attributed to anatectic metamorphic processes under low-aH 2O fluid conditions during a metamorphic event. These varieties of charnockite show that the required physical conditions of their genesis can be achieved through a number of geological processes, providing some important implications for the classification of charnockites, and for the interpretation of charnockite genesis in areas where poor exposure obscures field relationships. © 2012, China University of Geosciences (Beijing) and Peking University.

    High-spatial resolution carbon isotope analyses of natural graphite using secondary ion mass spectrometry (SIMS), together with conventional mass spectrometry techniques, demonstrate isotopic heterogeneity within single graphite crystals precipitated from a partially melted metamorphic rock. SIMS C-13/C-12 measurements were calibrated using an internal graphite standard previously analyzed by conventional isotope ratio mass spectrometry, which gave a reproducibility of 0.3aEuro degrees (1 sigma) at a spatial resolution of 2-3 mu m. This resolution helped to identify an unusual carbon isotope distribution in a single graphite crystal from a metapelitic leucosome, showing remarkable core to rim variations with sharp delta C-13 steps up to 10aEuro degrees. The results suggest that the graphite crystal grew from one edge to other forming layers perpendicular to the c-axis. The sharp isotopic steps indicate the presence of disequilibrium carbon isotope zoning in graphite and points to the possible existence of carbon isotope sector zoning. Intra-crystalline carbon isotope disequilibrium in graphite is believed to have resulted from the difference in diffusivity between C-12 and C-13 in the growth medium to the interface of graphite precipitation in different growth sectors.

    We report here new experimental data on equilibrium carbon isotope fractionation between graphite/diamond and iron carbide melt at 5 and 10 GPa and in the temperature range between 1200 and 2000 degrees C. Carbon isotope equilibrium was tested using morphological features of graphite and also by performing a longer duration experiment, both of which suggested that equilibrium carbon isotope fractionation is present. The results suggest that iron carbide melt will preferentially accumulate C-12 rather than C-13. An equilibrium temperature dependent fractionation between iron carbide melt and graphite/diamond is proposed based on the relationDelta C-13((gr/dia - iron carbide melt)) = 8.85{10(6)/T-2(K)} + 0.99.Our results are consistent with the carbon isotope distribution between graphite and cohenite (Fe3C) observed in iron meteorites. We propose that temperature-dependent fractionation of carbon isotopes between iron carbide melt and graphite/diamond might have created a "C-12-enriched core" with a significant difference in the distribution of carbon isotopes between the carbon in the metallic core and bulk silicate Earth during the accretion and differentiation of early Earth. Recent findings of low delta C-13 carbonados and diamonds of deep mantle origin supports the presence of a C-12 enriched source. The possible presence of a reservoir of C-12-enriched carbon in the Earth's core implies that it can generate large perturbations in the surface and shallow carbon-isotope system by the flux of lighter carbon from the core-mantle boundary.

    Carbon isotope exchange between calcite and graphite is a useful and reliable geothermometer for medium- to high-grade marbles. However, in rare instances, such as at Naxos, Greece, apparent disequilibrium carbon isotope fractionation between calcite and graphite has been previously reported. In this study, new results are presented on the morphological features, X-ray diffraction studies, Raman spectroscopic studies, and carbon isotope studies of graphite. Three morphologically distinct graphite types are identified. The first type is fine grained with distinct polygonal crystal aggregates having smooth pinacoid faces. The second type consists of large botryoidal aggregates with typical crystal overgrowth features, and the third type is "normal" large platy crystals associated with phlogopite. Graphite morphological features using an FE-SEM suggests that the botryoidal aggregates are composed of complexly intergrown and stacked graphite layers, comprised of cone-helix structures. Different types of graphite display distinct Lc(002) and DG values as well as a sharp first-order Raman peak at similar to 1580 cm(-1) with disordered bands. The presence of Raman disordered bands in fine-grained well-crystallized graphite is attributed to edge effects. Carbon isotope analysis of graphite reveals that marble with fine-grained well-crystallized graphite show a consistent isotope fractionation with the calcite, which perfectly match temperature estimates based on the mineral isograds. In contrast, coarse botryoidal graphite gives heterogeneous carbon isotope values (about a few per mill) and show anomalous carbon isotope fractionation between the calcite and graphite. The graphite associated with phlogopite also shows variations in the carbon isotope values. Combining morphologic, crystallographic, and carbon isotopic data we conclude that the variations in carbon isotopic composition were caused by the overgrowth of graphite on the preexisting grain and that morphological observations and structural characterizations of graphite crystals is a key for predicting isotopic equilibration during metamorphism.

    Corundum in direct contact with quartz and associated with andalusite has been found as an inclusion in alkali feldspar obtained from a leucosome, which forms a part of migmatized pelitic granulite from the Kerala Khondalite Belt, southern India. Thermodynamically, corundum + quartz is metastable relative to andalusite. Textural features suggest that it is a rare example of an arrested reaction corundum + quartz -&gt; andalusite which may have been triggered off by the introduction of H2O-rich fluids along the cracks of the host alkali feldspar during the uplift and cooling of the leucosome. The metastable corundum + quartz association most likely originated during the crystallization of the Al2O3-rich leucosome melt when early corundum came into contact with later quartz under conditions with a relatively low H2O activity.

    Calcite-dolomite solvus geothermometry is a versatile method for the estimation of metamorphic temperature because of its simplicity. However, in medium- to high-grade metamorphic rocks the accuracy of estimating temperature by the integration of unmixed dolomite and calcite is hampered by the heterogeneous distribution of unmixed dolomite, difficulties in distinguishing between preexisting and exsolved dolomite and demarcating grain boundaries. In this study, it is shown that calcite-dolomite solvus thermometry can be applied to calcite inclusions in forsterite and spinel for the estimation of peak metamorphic temperature in granulite facies marbles from Skallevikshalsen, East Antarctica. The marbles are comprised of a granoblastic mineral assemblage of calcite + dolomite + forsterite + diopside + spinel + phlogopite +/- apatite, characteristic of granulite facies metamorphic conditions. Forsterite, spinel and apatite frequently contain 'negative crystal' inclusions of carbonates that display homogeneously distributed dolomite lamellae. On the basis of narrow ranges of temperature (850-870 degrees C) recorded from carbonate inclusions compared with the range from matrix carbonate it is regarded that the inclusion carbonates represent a closed system. Furthermore, this estimate is consistent with dolomite-graphite carbon isotope geothermometry, and is considered to be the best estimate of peak metamorphic temperature for this region. Matrix calcite records different stages of retrograde metamorphism and re-equilibration of calcite that continued until Mg diffusion ceased at similar to 460 degrees C. Electron backscattered diffraction (EBSD) results together with morphological features of unmixed coarse tabular dolomite suggest anisotropic diffusion and mineral growth are influenced by crystallographic orientation. Identification of sub-grain boundaries and formation of fine-grained unmixing in calcite rims suggest the presence of grain boundary fluids in the late retrograde stages of metamorphic evolution. These results, thus, demonstrate the usefulness of carbonate inclusion geothermometry in estimating the peak metamorphic temperatures of high-grade terranes and the application of EBSD in understanding the unmixing behaviour of minerals with solid solutions.

    Kyanite and andalusite are newly found in migmatized pelitic granulites from the Kerala Khondalite Belt, Southern India. Anhedral tiny grains of kyanite included within altered cordierite were interpreted as possible remnants of prograde metamorphism of the granulites within the kyanite stability field. Andalusite shows two distinct modes of occurrence; some are of magmatic origin and others are formed as partial replacement products of alkali-feldspar and plagioclase mainly in leucosomes. Our data put new constraints not only on the P-T path followed by the granulites but also on the correlation between the Gondwana fragments. The Kerala Khondalite Belt is closely correlated with the Southwestern Group (southwestern part of the Highland Complex) in Sri Lanka.

Raman analyses of primary graphite flakes in close association with spinel and phlogopite confirm the highly crystalline nature. The carbon isotope composition ranges from -7 parts per thousand to -9.8 parts per thousand typical of mantle-derived graphite. A genetic model is proposed ill which carbon was derived from a reduced juvenile Mantle Source linked to the genesis of volatile rich ultramafic rocks in ACSZ.

    Characterization of fluid inclusions in graphite-bearing charnockites from the southwestern part of the Madurai Granulite Block in southern India reveals a probable relation with the formation and break down of graphite during the high-grade metamorphism. The first-generation monophase pure CO2 inclusions, the composition of which is confirmed by laser Raman spectroscopy, recorded moderate density (0.77-0.87 g/cc) corresponding to low tapping pressure (around 2 kb) than that of the peak granulite-facies metamorphism. The precipitation of graphite, as inferred from graphite inclusions and delta C-13 values of the graphite from the outcrops, is interpreted as the cause of this lowering of fluid density. An intermediate generation of pseudosecondary inclusions resulted from the re-equilibration or modification of the first-generation fluids and the CO2. formed is interpreted to be the oxidation product from graphite. The youngest generation of fluids which caused widespread retrogression of the granulites is a low-temperature (similar to 350 degrees C) high-saline (32.4-52.0 wt% NaCl equivalent) brine. Carbon isotope data on the graphite from the charnockites show delta C-13 values ranging from -11.3 to -19.9 parts per thousand, suggesting a possibility of mixing of carbon sources, relating to earlier biogenic and later CO2 fluid influx. Combining the information gathered from petrologic, fluid inclusion and carbon stable isotope data, we model the fluid evolution in the massive charnockites of the southwestern Madurai Granulite Block.

    Precise chemical composition, including Fe3+ and H, of biotite from a pegmatite dike and its host granulite from the Kerala Khondalite Belt of SE India has been determined using a multi-technique approach involving EMP, SIMS, Mossbauer, and C-H-N elemental analysis. Biotite in these rocks formed at T> 800-850 degrees C and P = 5 +/- 1 kbar.The full analyses were normalized on the basis of [O12-(x+y+z)(OH)(x)ClyFz]. Biotite in the pegmatite is Ti-, F-, and Cl-rich (0.33, 0.46, and 0.16 apfu, respectively), H2O-Poor (OH = 0.86 pfu), has X-Mg= 0.49 and Fe3+/Fe-tot <= 3%. The low octahedral vacancies (0.06 pfu) and the high oxygen content in the hydroxyl site (OH + F + Cl = 1.49 pfu) confirm the role of the Ti-oxy substitution as a major exchange vector in these high-T biotites.In the host granulite, fine-grained biotite is Fe3+-free, has low Cl (0.03 apfu), and more variable composition, with Ti, F, and X-Mg in the ranges 0.26-0.36, 0.52-0.67, and 0.67-0.77, respectively. The number of octahedral vacancies is relatively large (0.10-0.18 pfu) and the sum of volatiles (OH + F + Cl) varies from 1.71 to 2.06 pfu. Systematic variations of X-Mg are a function of the microstructural position and are in agreement with retrograde exchange reactions: biotite included in or in contact with garnet has the maximum values, whereas crystals in the matrix have the minima. Titanium has systematic negative correlations with F, X-Mg, and (OH + F + Cl), whereas Al and octahedral vacancies are virtually constant.These trends indicate that the Ti-vacancy, along with substitutions involving Al, cannot explain the observed short-scale variations. Conversely, the Ti-oxy exchange appears to be active, resulting from combination of two vectors: the more conventional hydroxylation Ti4+ + 2O(2-) = (Fe,Mg)(2+) + 2OH(-) and the "fluorination" Ti4+ + 2O(2-) = (Fe,Mg)(2+) + 2F(-). The systematic retrograde redistribution involves not only Fe and Mg as commonly observed, but also Ti, F, and H, in a way such to eliminate the primary Ti-oxy component of biotite.

    In both palaeoenvironmental and palaeogeographical studies, Antarctica plays a unique role in our understanding of the history of the Earth. It has maintained a unique geographical position at the South Pole for long periods. As the only unpopulated continent, the absence of political barriers or short-term economic interests has allowed international collaborative science to flourish. Although 98% of its area is covered by ice, the coastal Antarctic region is one of the wellstudied regions in the world. The integrity and success of geological studies lies in the fact that exposed outcrops are well preserved in the low-latitude climate. The continuing programme of the Japanese Antarctic Research Expedition focuses on the geology of East Antarctica, especially in the Dronning Maud Land and Enderby Land regions. Enderby Land preserves some of the oldest Archaean rocks on Earth, and the Mesoproterozoic to Palaeozoic history of Dronning Maud Land is extremely important in understanding the formation and dispersion of Rodinia and subsequent assembly of Gondwana. The geological features in this region have great significance in defining the temporal and spatial extension of orogenic belts formed by the collision of proto-continents. Present understanding of the evolution of East Antarctica in terms of global tectonics allows us to visualize how continents have evolved through time and space, and how far back in time the present-day plate-tectonic regime may have operated. Although several fundamental research problems still need to be resolved, the future direction of geoscience research in Antarctica will focus on how the formation and evolution of continents and supercontinents have affected the Earth's environment, a question that has been addressed only in recent years. © The Geological Society of London 2008.

    Spectacular reaction textures in poikiloblastic scapolitite boudins, within marbles in the continental crust exposed in the Lutzow-Holm Complex, East Antarctica, provide insights into the changing fluid composition and movement of fluid along grain boundaries and fractures. Petrographic and geochemical features indicate scapolite formation under contrasting fluid compositions. Core composition of scapolite poikiloblasts (Scp(I)) are marialitic (Cl = 0.7 apfu) whereas rims in contact with biotite or clinopyroxene are meionite rich. Fine-grained recrystallized equigranular scapolite (Scp(II)) shows prominent chemical zoning, with a marialitic core and a meionitic rim (Cl = 0.36 apfu). Scapolite poikiloblasts are traversed by Scp(III) reaction zones along fractures with compositional gradients. Pure CO2 fluid inclusions are observed in healed fractures in scapolite poikiloblasts. These negative crystal-shaped fluid inclusions are moderately dense, and are believed to be coeval with Scp(III) formation at temperatures &gt; 600 degrees C and a minimum pressure of c. 3.8 kbar. Grain-scale LA-ICPMS studies on trace and rare earth elements on different textural types of scaplolites and a traverse through scapolite reaction zone with compositional gradient suggest a multistage fluid evolution history. Scp(I) developed in the presence of an internally buffered, brine-rich fluid derived probably from an evaporite source during prograde to peak metamorphism. Recrystallization and grain size reduction occurred in the presence of an externally sourced carbonate (CaCO3)-bearing fluid, resulting in the leaching of Cl, K, Rb and Ba from Scp(I) along fractures and grain boundaries. Movement of fluids was enhanced by micro-fracturing during the transformation of Scp(I) to Scp(III). Fractures in fluorapatite are altered to chlorapatite proving evidence for the pathways of escaping Cl-bearing fluids released from Scp(I). The present study thus provides evidence for the usefulness of scapolite in fingerprinting changing volatile composition and trace element contents of fluids that percolate within the continental crust.

    The supracrustal Kerala Khondalite Belt (KKB; southern India) constitutes an important but little understood terrain in the evolution of East Gondwana. Here we report SHRIMP U-Pb zircon and titanite ages for a suite of metasedimentary rocks from the KKB. Metamorphic ages at 530.2 +/- 4.4 and 525 +/- 4.5 Ma were obtained from metapelitic and metapsammitic migmatites, respectively. These ages are interpreted to date peak metamorphism because both rock types have extensively melted under granulite-facies conditions. A similar age (520 +/- 4.7 Ma) was obtained from titanite from a granulite-facies calc-silicate rock. These ages are within error of SHRIMP ages for granulite-facies assemblages in Lutzow-Holm Bay, East Antarctica, the Highland and Wanni Complexes of Sri Lanka, and Southern Madagascar. We propose that this timing reflects a short span (similar to10 m.yr.) of high-temperature granulite-facies metamorphism and concomitant widespread migmatization that marks the final stage of collision between East and West Gondwana.

    Graphite from deposits occurring in the high-grade metamorphic rocks and their larteritized equivalents of the Thodupuzha-Kanjirappally Belt in Madurai Granulite Block, southern India is structurally fully ordered (crystallite size, Lc((002)) ranging from 469 to 749 angstrom), possess high degree of graphitization (DG value ranging from 105 to 267 angstrom) and reflect crystallization at high temperature (700 +/- 100 degrees C). Raman spectra of graphite display profiles corresponding to high crystallinity and high structural ordering. The high temperature crystallinity characteristics of graphite were not obliterated during retrogression of granulites to amphibolite facies gneisses. Preliminary carbon stable isotope results show a spread in isotope values from -11.8 to -26.8 parts per thousand, which suggest more than one sources for carbon. The lighter carbon isotope values are suggestive of biogenic origin, whereas the heavier ones are probably fluid precipitated graphite.

    Graphite in deep crustal enderbitic (orthopyroxene + garnet + plagioclase + quartz) granulites (740 degrees C, 8.9 kb) of Nilgiri hills, southern India were investigated for their spectroscopic and isotopic characteristics. Four types of graphite crystals were identified. The first type (Gr(I)), which is interstitial to other mineral grains, can be grouped into two subtypes, Gr(IA) and Gr(IB). Gr(IA) is either irregular in shape or deformed, and rough textured with average delta C-13 values of -12.7 +/- 0.4 parts per thousand (n = 3). A later generation of interstitial graphite (Gr(IB)) shows polygonal crystal shapes and highly reflecting smooth surface features. These graphite grains are more common and have delta C-13 values of -11.9 +/- 0.3 parts per thousand (n = 14). Both subtypes show well-defined Raman shifts suggesting a highly crystalline nature. Cores of interstitial graphite grains have, on average, lower delta C-13 values by similar to 0.5 parts per thousand compared to that of the rim. The second type of graphite (Gr(II)) occurs as solid inclusions in silicate minerals, commonly forming regular hexagonal crystals with a slightly disordered structure. The third type of graphite (Gr(III)) is associated with solid inclusions (up to 100 mu m) that have decrepitation halos of numerous small (&lt; 15 mu m) satellite fluid inclusions of pure CO2 with varying density (1.105 to 0.75 g/cm(3)). The fourth type of graphite (Gr(IV)) is found as daughter crystals within primary type CO,fluid inclusions in garnet and quartz. These fluid inclusions have a range of densities (1.05 to 0.90 g/cm(3)), but in general are significantly less dense than graphite-free primary, pure CO2 fluid inclusions (1.12 g/cm(3)). Raman spectral characteristics of graphite inside fluid inclusions suggest graphite crystallization at low temperature (similar to 500 degrees C). The precipitation of graphite probably occurred during the isobaric cooling of CO2-rich peak metamorphic fluid as a result of oxyexsolution of oxide phases. The oxyexsolution process is evidenced by the magnetite-ilmenite granular exsolution textures and the systematic presence of numerous micron-sized rutile and other oxide inclusions in association with fluid inclusions within garnet, plagioclase, and quartz.
    The carbon isotope compositions of coexisting CO2 (in fluid inclusions) and graphite show a fractionation (alpha(CO2-gr)) of -6 parts per thousand in Garnet, consistent with the existing theoretical estimates of alpha(CO2-gr) at 800 degrees C. A subsequent generation of CO2 inclusions trapped in matrix quartz and quartz segregation have higher values, -4 parts per thousand and -2.9 parts per thousand respectively. Graphite in quartz segregations also has higher delta C-13 values (-9.8 parts per thousand) than those in enderbite (-12.7 parts per thousand). Micro-graphite crystals included in garnet, quartz (enderbite), and quartz (segregation) have average delta C-13 values of -11.1, -10.4, and -8.7 parts per thousand respectively, indicating progressive enrichment in C-13 with a decrease in temperature of recrystallization of respective minerals. This progressive enrichment is also observed in carbon isotope compositions of fluid inclusion CO2, suggesting isotopic equilibrium during Graphite precipitation from CO2 fluids. Thus, the carbon isotope record preserved in these rocks by the interstitial graphite, CO2 fluid in enderbite, graphite inicrocrystals, graphite in quartz segregation, and CO2 fluid in quartz segregation, suggests a temperature-controlled isotopic evolution. This evolution is in accordance with a closed system Rayleigh-type graphite precipitation process which progressively enriched residual CO2 in C-13. Copyright (c) 2005 Elsevier Ltd.

  • The role of aqueous silica concentration in controlling the mineralogy during high temperature contact metamorphism: A case study from Fuka contact aureole, Okayama, Japan 査読

    The contact aureole at Fuka, Okayama, Japan is peculiar for the occurrence of extensive high-temperature skarn resulting from the intrusion of Mesozoic monzodiorite into Paleozoic marine limestone. The occurrence is also notable for the finding of ten new minerals, of which five are calcium-boron-bearing minerals, and scores of other rare minerals. Skarn formation at Fuka can be classified into three major types 1. Grossular-vesuvianite-wollastonite endoskarn, 2. Gehlenite-exoskarns, and 3. Spurrite-exoskarns. Grossular-vesuvianite-wollastonite endoskarn forms a narrow zone (few centimeter width) separating the exoskarn and the igneous intrusion. It is also found, developed independently, along contacts of the younger basic intrusive dykes and limestone in the region. The gehlenite-exoskarns, in most cases, are spatially associated with igneous intrusion and are extensive (decimeter to meter thick). However, exceptions of independent gehlenite dikes are also observed. Retrogression of the gehlenite endoskarns results in the formation of hydrogrossular and/or vesuvianite. Accessory phases include schrolomite and perovskite. The predominantly monomineralic spurrite-exoskarn was formed in the outer zone of the gehlenite-skarn parallel to the contact as well as independent veins, dikes and tongues. The spurrite-exoskarn may extend tens of meters. Spurrite coexists with tilleyite or rankinite, although larnite is absent. Idiomorphic gehlenite and vesuvianite are the most common accessory phases observed. Retrograde hydration of spurrite to foshagite, scawtite and hillebrandite is commonly observed as veins and alteration zones within the spurrite exoskarn.
    Petrogenetic grids were constructed using "THERMOCALC" for the observed mineral assemblage in the spurrite skarn. Mineral-fluid equilibrium in the CaO-SiO2-CO2 system was computed, considering the metasomatic input of aqueous silica. Phase diagram analysis in the form of T-X-CO2 grids with varying silica activity indicated that the stability field of spurrite is strongly controlled by the activity of silica in the fluid. Optimum silica concentration in the fluid was between 9.1 x 10(-4) and 4.5 x 10(-3) mol/liter, above which wollastonite becomes stable, whereas further reduced silica activity will generate larnite. Appropriate temperature condition for the formation of spurrite is between 850 degrees C and 1080 degrees C at an X-CO2 fluid composition of 0.05 to 0.42. At temperature conditions lower than 850 degrees C, the spurrite stability field becomes narrow, with low CO2 activity. The formation of extensive spurrite-exoskarn suggests that the silica activity, temperature and fluid composition remained within the spurrite stability field. Petrogenetic analysis of phase diagrams suggests that the exoskarn formation at Fuka contact aureole was robustly controlled by the activity of silica in the high temperature metasomatic fluid.

    A 2 cm long and 0.8 cm thick, single graphite crystal embedded in quartz, feldspar, and orthopyroxene of a gramilite-facies metamorphic rock from southern India exhibits unique homogeneity in delta(13)C values along layers parallel to the (0001) surface and smooth unidirectional variation of about 1parts per thousand along the c-crystallographic axis. The fluid-precipitated graphite shows isotope homogeneity indicative of crystal growth along the (0001) plane. The C-isotope data along with the textural features suggest that the formation of graphite initiates in a layer perpendicular to the c-axis, possibly by a spiral growth mechanism. The initial layer is followed layer after layer, until the final stages of graphite growth. A second stage of graphite growth unrestricted by surrounding minerals is inferred from the un-deformed idiomorphic hexagonal form of the overgrown crystals. The C-isotope values in the overgrown rim of the crystal are lowered by about 2parts per thousand, suggesting a multistage precipitation. Morphologic and stable isotope studies thus confirm uniform crystal growth of graphite recording an isotope evolution pattern relating to fractionation from a fluid in an infinite reservoir during the main crystal formation. Spiral growth parallel to the (0001) face can explain the perfect uniformity of stable isotope composition in a single layer, whereas the variation across the (0001) surface gives insights into the time-integrated fluid evolution attending the crystal growth.

    The Digana metagranitoid, situated within the Digana shear zone, a critical junction between the Highland and Wanni complexes of Sri Lanka, hosts a variety of graphite types with structural evidence showing formation during different stages prior to and after deformational events affecting this terrain. Here we discuss their occurrence, association and stable isotopes. The carbon isotopes of graphite reported in this study from the Sri Lankan high-grade metamorphic terrain differ significantly from the composition of graphite reported elsewhere in other Precambrian terrains. The stable isotope composition from random crystals depicts an enriched carbon isotopic composition in the range -1.6 parts per thousand to -8 parts per thousand, suggesting precipitation by reduction from CO2-rich fluids. Intracrystalline microscale traverses made on graphite crystals indicate the delta(13)C composition of the rims becoming progressively lighter in C-13, in metagranitoid hosted samples, with the variation reaching up to 1.5 parts per thousand, consistent with the changing fluid regimes induced by decreasing temperature during the graphite growth, and shows the preservation of core at higher temperatures. A highly enriched carbon isotopic composition ( -0.6 parts per thousand) with a rimward enrichment of C-13 observed in migmatites, contrary to the values in metagranitoid, indicates preferential enrichment of heavy isotopes as a result of the partial melting and dissolution/reprecipitation of graphite. The oxygen isotopic composition of a quartz-calcite vein show values in the range 18.5 parts per thousand to 20 parts per thousand, typical for recycled crustal source. The tight constraint in the isotopic data from different graphite types studied indicates a homogeneous fluid source for the deposits. Prolonged fluid flow in this region is envisaged in this study, which is related to the multistage deformation of the crustal scale shear zone. (C) 2002 Elsevier Science B.V. All rights reserved.

    Fluid infiltration into active faults and shear zones is usually studied in middle to upper crustal environment. Circulating fluids deposit fine-grained sediments like clay and carbonate material into cracks within the fault zone. Such crack-fill fine-grained material, calcite veins, and oxidized/weathered open cracks are well observed in the drill cores, from near-surface to a depth of 1800 m, in the Nojima fault zone, Japan, which triggered the 1995 M7.2 Kobe earthquake. Powder X-ray diffraction analysis indicates that the crack-fill fine-grained materials are mainly composed of siderite, calcite, laumontite, and fine-grained clasts of granitic rock. Isotopic analyses of carbonate material within the fine-grained materials and calcite veins reveal variable delta(13)C (SMOW) values ranging from 19.3parts per thousand to 27.7parts per thousand and delta(13)C (PDB) values of -4.6parts per thousand to -18.5parts per thousand which are consistent with those of typical meteoric and seawater. C-14 dates of 10 calcite vein samples range from 35.0 to 58.4 kyr B.P.
    Geological, petrological, stable isotopic, and C-14 data suggest that these crack-fill fine-grained materials and calcite veins and brown open cracks were developed by the repeated infiltration of O-2- and CO2-bearing meteoric and seawater downward into the deep Nojima fault zone during the last 35-60 kyr. We propose a seismic fault suction-pumping model to interpret the infiltration of subsurface waters being carried down into the deep fault zone by rapid potential change during episodes of seismic faulting.

    Scheelite mineralization in the granulite-facies supracrustal sequences of the Kerala Khondalite Belt, Southern India is reported. The supracrustal sequences where the mineralization is found comprise granulite-grade metasediments which underwent metamorphism at similar to550 Ma. The mineralization is assumed to have formed by late-stage metasomatism that overprinted the regional metamorphism of the country rock (garnet-biotite gneiss) and occurs along a quartz vein that intrudes the regional foliation. The paragenetic data from the vein demonstrate unambiguously a separate cycle of hydrothermal activity, resulting in metasomatism and mineralization. Scheelite is found in both the altered host rock along he foliation plane and in the quartz vein. Fluid inclusions preserved in the vein suggest that the mineralizing fluids were saline-aqueous in composition, while those in the country rocks were predominantly CO-rich. The mineral chemistry and bulk-rock chemical composition of the mineralized domain reveal the unusual enrichment of Ca in the mineralised zone with the depletion of K. We propose that fluid discharging from a crystallizing deep-seated magma, mixing with deep circulating Ca-bearing palaeo-groundwater gave rise to the deposition of scheelite. The scheelite mineralization and the quartz vein emplacement occurred after the Pan-African regional metamorphism.

    Nine marble horizons from the granulite facies terrane of southern India were examined in detail for stable carbon and oxygen isotopes in calcite and carbon isotopes in graphite. The marbles in Trivandrum Block show coupled lowering of delta(13)C and delta(18)O values in calcite and heterogeneous single crystal delta(13)C values (-1 to -10parts per thousand) for graphite indicating varying carbon isotope fractionation between calcite and graphite, despite the granulite facies regional metamorphic conditions. The stable isotope patterns suggest alteration of delta(13)C and delta(18)O values in marbles by infiltration of low delta(13)C-delta(18)O-bearing fluids, the extent of alteration being a direct function of the fluid-rock ratio. The carbon isotope zonation preserved in graphite suggests that the graphite crystals precipitated/recrystallized in the presence of an externally derived CO2-rich fluid, and that the infiltration had occurred under high temperature and low f(O2) conditions during metamorphism. The onset of graphite precipitation resulted in a depletion of the carbon isotope values of the remaining fluid + calcite carbon reservoir, following a Rayleigh-type distillation process within fluid-rich pockets/pathways in marbles resulting in the observed zonation. The results suggest that calcite-graphite thermometry cannot be applied in marbles that are affected by external carbonic fluid infiltration. However, marble horizons in the Madurai Block, where the effect of fluid infiltration is not detected, record clear imprints of ultrahigh temperature metamorphism (800-1000 degreesC), with fractionations reaching &lt;2 parts per thousand. Zonation studies on graphite show a nominal rimward lowering delta C-13 on the order of 1 to 2 parts per thousand. The zonation carries the imprint of fluid deficient/absent UHT metamorphism. Commonly, calculated core temperatures are &gt;1000 degreesC and would be consistent with UHT metamorphism.

    An extensive humite-bearing marble horizon within a supracrustal sequence at Ambasamudram, southern India, was studied using petrological and stable isotopic techniques to define its metamorphic history and fluid characteristics. At peak metamorphic temperatures of 775 +/- 73 degreesC, based on calcite-graphite carbon isotope thermometry, the mineral assemblages suggest layer-by-layer control of fluid compositions. Clinohumite + calcite-bearing assemblages suggest X-CO2 (0.4 (at 700 degreesC and 5 kbar), calcite + forsterite + K-feldspar-bearing assemblages suggest X-CO2 &gt; 0.9 (at 790 degreesC); and local wollastonite + scapolite + grossular-bearing zones formed at X-CO2 of c. 0.3. Retrograde reaction textures such as scapolite + quartz symplectites after feldspar and calcite and replacement of dolomite + diopside or tremolite + dolomite after calcite + forsterite or calcite + clinohumite are indicative of retrogression under high X-CO2 conditions. Calcite preserves late Proterozoic carbon and oxygen isotopic signatures and the marble lacks evidence for extensive retrograde fluid infiltration, while during prograde metamorphism the possible infiltration of aqueous fluids did not produce significant isotopic resetting. Isotopic zonation of calcite and graphite grains was likely produced by localized CO2 fluid infiltration during retrogression. Contrary to the widespread occurrence of humite-marbles related to retrograde aqueous fluid infiltration, the Ambasamudram humite-marbles record a prograde-to-peak metamorphic humite formation and retrogression under conditions of low X-H2O.

    Scapolites developed variably in the deep-seated metagabbros of the Kohistan Are, north Pakistan, were investigated to evaluate the distribution and migration of C-O-H-S fluid and origin of carbon in the lower crust. Scapolites can be classified, based on their distinct difference in occurrence and chemical composition, into carbonate type and sulfate-rich type. Carbonate-type scapolites occur around carbonate pods in the layered gabbros at the mid-crustal levels and were formed by an increase in the CaO activity in the country rocks and simultaneous decarbonation of calcite. Predicted equilibrium CO2 mole fraction in fluid (X-CO2) is sufficiently low to be consistent with removal of CO2. Sulfate-rich scapolites occur in the garnet-bearing granulites at the lower crustal level and were formed by breakdown reactions of garnet and plagioclase under relatively higher CO2 activity (a(CO2)) and oxygen fugacity. The carbon isotopic composition (delta C-13) in carbonate scapolite is equivalent to the juvenile mantle (-5 to -6 parts per thousand), whereas sulfate-rich scapolite has heavy carbon stable isotope values close to 0 parts per thousand. These results reveal that carbonate scapolite was formed by decarbonation and metasomatism of igneous carbonate pods with the host metagabbros under granulite facies conditions, and sulfate-rich scapolites were formed by infiltration of CO2-rich fluid derived from decarbonation of carbonate-bearing sediments in the subducting slab.

    The Kerala Khondalite belt is a Proterozoic metasupracrustal granulite facies terrain in southern India comprising garnet-biotite gneiss, garnet-sillimanite gneiss and orthopyroxene granulites as major rock types. Gale-silicate rocks and marbles, occurring as minor lithologies in the Kerala Khondalite Belt, show different mineral assemblages and reaction histories of which indicate a metamorphic P-T- fluid history dominated by internal fluid buffering during the peak metamorphism, followed by external fluid influx during decompression. The carbon and oxygen isotopic compositions of calcite from three representative metacarbonate localities show contrasting evolutionary trends. The Ambasamudram marbles exhibit carbon and oxygen isotope ratios (delta C-13 similar to 0 parts per thousand and delta O-18 similar to 20 parts per thousand) typical of middle to late Proterozoic marine carbonate sediments with minor variation ascribed to the isotopic exchange due to the devolatilization reactions. The delta C-13 and delta O-18 values of similar to -9 parts per thousand and 11 parts per thousand, respectively, for calcite from calc-silicate rocks at Nuliyam are considerably low and heterogeneous. The wollastonite formation here, possibly corresponds to an earlier event of fluid infiltration during prograde to peak metamorphism, which resulted in decarbonation and isotope resetting. Further, petrologic evidence supports a model of late carbonic fluid infiltration that has partially affected the calc-silicate rocks, with subsequent isotope resetting, more towards the contact between calc-silicate rock and charnockite. At Korani, only oxygen isotopes have been significantly lowered (delta O-18 similar to 13 parts per thousand) and the process involved might be a combination of metamorphic devolatilization accompanied by an aqueous fluid influx, supported by petrologic evidence. The stable isotope signatures obtained from the individual localities, thus indicate heterogeneous patterns of fluid evolution history within the same crustal segment.

    Carbon isotope thermometry between calcite and graphite has been applied to the granulite facies marble assemblages in the Skallen region of the Lutzow-Holm Bay, East Antarctica. The carbon and oxygen isotope values of calcite from five samples, which are interlayered with pelitic and charnockitic assemblages, suggest within-layer isotopic equilibrium. Textural studies of graphite crystals indicate two types; one smooth, highly reflecting regular shaped graphite and the other rough, dull and irregular shaped graphite. The delta(13)C values of the dull surfaced graphite are lower by about one per mil than the high reflecting graphite. Carbon isotopic compositions suggest that graphite with lower delta(13)C values is confined to the surface layer of the graphite crystal. This is indicative of a later-stage overgrowth during retrograde metamorphism. delta(13)C of dull graphite was excluded in calculating the temperature of peak metamorphism. Temperatures of similar to 850 degrees C correspond to the peak metamorphic temperatures for the region. This temperature estimate is consistent with the regional metamorphic conditions based on cation exchange thermometry in pelitic granulites and is interpreted to be more precise.

    Melt inclusions in olivine and pyroxene phenocrysts in kersantite and camptonite at Chhaktalao in Madhya Pradesh, India are mainly of the evolved type forming daughter minerals of olivine, pyroxene, plagioclase, spinel, mica, titanomagnetite and sulphides. Heating studies exhibit a temperature range from 1215 degrees to 1245 degrees C for the melt inclusions in olivine in camptonite and 1220-1245 degrees C for olivine in kersantite. The temperature for melt inclusions in pyroxene ranged from 1000 degrees to 1150 degrees C in camptonite and 850-1100 degrees C for pyroxene in kersantite. The bubble inside these melt inclusions is mainly CO2. The T(h)degrees C of CO2 into liquid phase occurred between 26 degrees and 31 degrees C in olivine and 25-30 degrees C: in pyroxene from kersantite and camptonite. The maximum density estimated is 0.72 g/cm(3) and the minimum is 0.45 g/cm(3). The depth of entrapment of the melt inclusion is estimated between 10-15 km. The pressure of entrapment of melt inclusion in olvine is 4.6 kbar where as that in pyroxene is 3.7 kbar. The lamprophyres in the Chhaktalao area are considered to be derived from low depth and low pressure region, possibly within spinel Iherzolite zone. (C) 2000 Elsevier Science Ltd.

    Ultrahigh-temperature (UHT) metamorphism in the Madurai Block of the southern Indian granulite terrain has been verified using the calcite-graphite isotope exchange thermometer. Carbon isotope thermometry has been applied to marbles from a locality near the reported occurrence of sapphirine granulites that have yielded temperature estimates of around 1000 degrees C. The delta(13)C and delta(18)O values of calcite are homogenous, implying equilibration of the isotopes during metamorphism. However, the delta(13)C values of Single graphite crystals show variations in the order of 1%o within a hand specimen. Detailed isotopic zonation studies indicate that graphite preserves either the time-integrated crystal growth history or reequilibrium fractionation during its cooling history. The graphite cores preserve higher delta(13)C values than the rims. The fractionation between calcite and graphite cores gives the highest metamorphic temperature of about 1060 degrees C, which matches the petrologically inferred temperature estimates in the high-magnesian pelites. The fractionation between graphite rims and calcite suggests a temperature of around 750 degrees C, which is interpreted to reflect retrograde cooling. This event is also observed in the sapphirine granulites. Calcite-graphite thermometry thus provides a useful tool to define UHT metamorphism in granulite terrains.

    Across a 1.2-mm-wide domain, a calcite crystal from a granulite-facies marble from East Antarctica exhibits microscale oxygen isotope heterogeneity that has been enhanced by channelized fluid flow. The oxygen isotope compositions range over 21 parts per thousand--a gigantic zonation. Calcite along a boundary with phlogopite has an average delta(18)O value of -5 parts per thousand; along a profile that extends about 700 mu m into the grain, the oxygen isotope composition remains constant, indicating equilibrium with source fluids of meteoric origin. Analyses of a transect away from the phlogopite show the delta(18)O values rising to +16 parts per thousand. The corresponding carbon isotope variation is only about 0.6 parts per thousand. Isotope heterogeneity is observed mainly in a phlogopite-rich zone where the delta(18)O values are lower (13 parts per thousand +/- 5 parts per thousand) than those away from the zone (17 parts per thousand +/- 1 parts per thousand). We inferred that preferential microfracturing and hydrothermal fluid flaw were the causes of the O-18 distribution, The constant values of both delta(18)O and delta(13)C for the distance of 700 mu m from the grain boundary suggest a solution-reprecipitation mechanism, whereas the smoothly increasing delta(18)O and decreasing delta(13)C values farther along the profile indicate a diffusion-controlled isotope exchange between the reprecipitated calcite and the original grain (core). Our results provide important evidence for the mechanism of isotope exchange between fluids and minerals and have major implications for microfracture-controlled fluid-flow processes in the Earth's crust.

    Carbonate-rich racks occur as E-W trending dyke-like bodies in the Deccan 'basalts at Chhaktalao area in the lower Narmada valley and show a structurally controlled mode of emplacement. Modal composition shows calcite as the dominent mineral (similar to 90%). Ankerite, apatite, altered olivine, augite and opaques account for the remaining percentage. Geochemically, these rocks show high CaO (&gt;50%) with low SiO2, TiO2, FeO* and K2O. Trace element concentrations are low compared to avenge carbonatites. Stable isotope studies show that delta(13)C (-1.74 parts per thousand to -2.8 parts per thousand) and delta(18)O (+12.75 parts per thousand to +13.35 parts per thousand) values do not compare with those of "primary igneous carbonatites" eventhough they fall within the wide range of "igneous carbonatites". These rocks can be considered only as carbonate-rich rocks and not as true carbonatites.

    Humite group minerals occur in the marbles of granulite grade at Ambasamudram, southern India. Detailed mineralogical and mineral chemical characterization indicate the mineral is a flourine-rich titanian-poor variety of clinohumite. Average M-Ti/Si values of 2.22 with typical XRD pattern indicate the mineral to be clinohumite. Petrological constraints on the clinohumite formation shows a high temperature (&gt;700 degrees C) and low a(CO2) during its formation. The fluorine content of these clinohumites is the highest reported in any environment, with F/(F+OH) ratio reaching a value of 0.70. The high fluorine content reflect the high P-T condition of formation. The OH content of the clinohumites is around 0.59 mole fraction. Preliminary FTIR spectra of the clinohumites show eight sharp absorption peaks between wave numbers 3700 and 3400 cm(-1) and a broad absorption band with a peak at 3840 cm(-1). The sharp peaks are due to OH in the clinohumite. The high fluorine content of the Ambasamudram clinohumites possibly resulted from the isochemical reactions involving (OH-F) silicates such as amphiboles or phlogopites. The internal fluid buffering is also supported by the stable isotope as well as the petrological studies of the marble assemblages.

    Scapolite-wollastonite-grossular bearing calc-silicate rocks from the Vellanad area in the Kerala Khondalite Belt (KKB) of Southern India preserve a number of reaction textures which help to deduce their P-T-fluid history. Textures include calcite + plagioclase +/- quartz symplectites after scapolite, grossular + quartz coronas between wollastonite and plagioclase, grossular coronas between wollastonite and plagioclase + calcite that replace former scapolite, and grossular blebs replacing anorthite + calcite + quartz pseudomorphs of scapolite. Garnet coronas are also observed between clinopyroxene and wollastonite or scapolite or plagioclase. The reactions, apart from those involving clinopyroxene, can be modelled in the simple CaO-Al2O3-SiO2-CO2 system and interpreted using partial reaction grids constructed for the activities of end-members in the analysed phases. The reaction topologies produced are good approximations for the peak as well as retrograde mineral assemblages and reaction textures. For the compositions of the phases present in this study, the medium pressure calc-silicate assemblages an defined by the stable pseudo-invariant points [Qtz], [Mei] and [Grs]. The textural features interpreted using these activity-corrected grids indicate a phase of isobaric cooling from about 835 degrees C to 750 degrees C at 6 kbar in the Vellanad area. This is inconsistent with earlier studies on other Lithologies from the KKB, most of which imply a post-peak P-T path involving near-isothermal decompression. However, as the temperatures obtained for the KKB from the calc-silicates are higher than those previously deduced from metapelites and garnet-orthopyroxene assemblages, the phase of near-isobaric cooling reported here is inferred to have proceeded prior to the onset of the decompression documented from studies of other rock types.

    Colour-coded compositional mapping under an electron microprobe provides useful information on chemical gradients within the domain of individual minerals. Here we apply this technique to granulite facies reaction texture's from a calc-silicate-charnockite interface at Nuliyam, southern Kerala, to understand the element mobility patterns and mass balance related to fluid-induced metasomatism during deep crustal metamorphism. The contact zone assemblage at Nuliyam is characterized by plagioclase + quartz symplectites after K-feldspar. From element mapping of this reaction interface on micron - scale, and from quantitative analyses of the individual mineral phases under an electron microprobe, we trace the diffusion of K, and addition of Na and Ca, through an open system migration during the influx of externally-derived CO2- rich fluids. Our study provides the first direct evidence for microscale chemical diffusion associated with CO2-induced charnockite formation in southern Kerala, and illustrates the potential of colour-coded compositional mapping in tracing element mobility patterns.

    This paper reports several new localities of wollastonite- and scapolite-bearing calc-silicate assemblages from the granulite-facies supracrustal Kerala Khondalite Belt (KKB), southern India. Based on mineralogy, these calc-silicate rocks are classified into four types: Type I, lacking wollastonite and grossular; Type II, wollastonite-bearing but grossular-absent; Type III, wollastonite- and grossular-bearing; and Type IV, dolomitic marbles. Detailed petrographic studies reveal a variety of reaction textures overprinting the polygonal granoblastic peak metamorphic assemblages in these rocks. The Type II calc-silicate rocks preserve reaction textures, including meionite breaking down to anorthite-calcite-quartz, wollastonite breaking down to calcite-quartz and meionite-quartz symplectites after K-feldspar and wollastonite. Type III calc-silicate rocks have porphyroblastic and coronal grossular. Grossular-quartz coronas separating wollastonite and anorthite and the development of grossular within the anorthite-calcite-quartz pseudomorphs of meionite form important retrograde reaction textures in this type. In Type IV dolomitic marble assemblages, meionite forming in grain boundaries of calcite and feldspars, forsterite rimmed by diopside-dolomite and the formation of grossular in feldspar-rich zones are the important textures. Calculated partial petrogenetic grids in the CaO-Al2O3-SiO2-CO2 system are used to deduce the pressure-temperature-fluid evolution of the calc-silicate rocks. The Type II assemblages provide CO2 activity estimates of &gt;0.5, with a peak metamorphic temperature of about 790 degrees C. Initial cooling followed by later CO2 influx can be deduced from reaction modelling in these calc-silicate rocks. Type III assemblages are characterized by internal fluid buffering throughout their tectonic history. The formation of coronal grossular indicates an initial cooling from peak metamorphic temperatures of about 830 degrees C deduced from vapour-absent meionite and grossular equilibria. Type IV marble assemblages also indicate internal fluid buffering followed by localized CO2 influx. Overall, the calc-silicate rocks of the KKB define peak metamorphic temperatures in the range of 790-850 degrees C, with an internally buffered fluid composition during the peak conditions. Initial cooling was followed by localized carbonic fluid influx that also post-dated decompression deduced from other rock types in the KKB. Copyright (C) 1996 Elsevier Science Ltd

    Orthopyroxene and wollastonite are critical minerals in the end-member models on granulite petrogenesis in the Earth's deep crust, and are considered to be mutually incompatible. We report here the occurrence, mineralogy and chemistry of wollastonites from calc-silicates in a number of new localities of the Kerala Khondalite Belt, southern India, where they are associated with orthopyroxene-bearing charnockites. While the charnockite mineral phase equilibria constrain X(co2) &gt; 0.85 to drive the orthopyroxene-forming reaction, the presence of wollastonite in the calc-silicates requires X(co2) to be &lt; 0.25. We provide mineral reaction and fluid inclusion evidence which suggests that wollastonite formation occurred under low X(co2) conditions during the prograde sector of a clockwise P-T path, whereas orthopyroxene stability and charnockite formation resulted under anhydrous conditions through the structurally controlled influx of CO2 along an isothermal decompression path. The wollastonite-and orthopyroxene-bearing assemblages described in this study have important implications in evaluating changing fluid regimes during deep crustal metamorphism.

    The granite pluton at Kalpatta in northern Kerala is a member of the Late Precambrian magmatic suite emplaced proximal to transcrustal faults in southern India. In this study, we report the find of fluorite mineralization within late pegmatite phase associated with the granite. Both purple and colourless fluorites are associated, with X-ray diffraction pattern indicating perfect crystalline nature. Wet chemical analyses show CaF2 contents of 92 and 96 % for purple and transparent fluorites respectively. Primary fluid inclusions in both fluorite categories belong to aqueous bi-phase type, with T(h) between 150-180-degrees-C, and salinity in the range of 3 to 9 wt. per cent NaCl equivalent. Qurtz associated with fluorite contains CO2-H2O inclusions with T(h(CO2)) between 8 to 15-degrees-C (density 0.85-0.90 g/cm3). The nature of mineralizing fluids suggests that fluorite crystallization occured from low temperature hydrothermal solutions derived as end-products of the frctionation of volatile- and alkli-enriched felsic magma. The mineralization is regarded as a finger-print of the alkaline affinity of Pan-African magmatism in Kerala.

    高温高圧実験とその合成試料や天然試料の分析を硫黄同位体分析システムを用いて行った。さらにレーザー加熱式ダイヤモンドアンビルセルを用いて、様々な出発物質を使用した実験を行い、以下の代表的な成果を得た。
    (1) 回収試料の硫黄同位体分別測定を行い、高温高圧条件下でのケイ酸塩-金属間の硫黄同位体分別への温度圧力効果の解明を試みた。全ての実験で金属相に重い硫黄34Sが富む結果が得られた。分別に対して、負の温度効果が見られたが、圧力効果は見られなかった。
    (2) 還元的な下部マントル環境下(90-120GPa、2000-2500K)における炭酸塩鉱物の安定性を、レーザー加熱式ダイヤモンドアンビルセルにより調べた。実験には、MgCO3または(Mg,Fe)CO3を封入した、鉄またはニッケル製の微小金属カプセルを用いた。実験の結果、120 GPaを超える高圧下では、還元的環境下でも炭酸塩が安定化する可能性が示唆された。
    (3) ハワイなどの海洋島玄武岩中に見られるオスミウム同位体異常の起源として、内核の成長に伴うRe, Os, Ptの分別が提案されている。これを明らかにするため、液体鉄-固体鉄間の強親鉄性元素の分配実験を60GPaまで行った。実験にはレーザー加熱式ダイヤモンドアンビルセルを用いた。二次イオン質量分析計を用いた上記三元素の定量分析に備え、主成分元素の定量および組織観察をEPMAを用いて行った。
    (4)Tahiti産のカンラン岩捕獲岩を用いたin situまたは全岩の白金族元素分析を行った。天然のカンラン岩試料にみられる全岩白金族元素濃度の大きな多様性の原因を探 るため、白金族元素の高温 高圧での挙動に関する実験的研究についてのレビューを進めている。さらに,カンラン岩捕獲岩を用いた全岩Os同位体分析が完了し、解析中である。

    本研究では、報告者が第46次南極観測隊に参加して採取してきた東南極リュツォホルム湾地域の大理石やカルクシリケート岩、グラファイトを含む泥質岩など炭素を含む岩石から、炭素循環解明のための基本的な鉱物化学、同位体地球化学的データを得た。変成作用は、最高変成度の温度・圧力条件下で、水の分圧と酸素の分圧も共に低い条件であり、特にカルクシリケート岩の解析から超高温変成作用を被ったことが明らかとなった。また本研究では、後退変成作用において、流体の関与により中程度の水分圧に変化させたことを示す鉱物の反応関係を見っけた。さらに、チタナイトのSHRIMP年代の測定から、510-470Maという値が求められ、これはこの地域の地殻の上昇過程での冷却と後退的な流体流入イベントの起きた年代を示している。
    大理石を構成する方解石の炭素と酸素同位体、及び、グラファイトの炭素同位体の研究を推進した。方解石-グラファイト間の炭素同位体地質温度計を適用し、最高変成度の変成温度において両者が炭素同位体平衡に達していたことを明らかにした。大理石のストロンチウム同位体組成は、かなり幅広い同位体値〔0.758-0.705〕をとり、これは堆積物の変質に由来するものである。この変質は、大理石の変成作用発達での流体と岩石の相互作用で起きたことが考えられる。
    大理石中の方解石、ドロマイト、アパタイトから得られた微小スケールの炭素・酸素同位体、及び、ストロンチウム同位体比の測定は、ゴンドワナ超大陸の集積過程においてリュツォホルム複合岩帯の深部地殻で起きた異なる時期の流体と岩石の相互作用を識別するのに役立つことを示した。さらに、東西のゴンドワナ大陸間に存在した当時のモザンビーク海の石灰岩の堆積年代は、750-830Maの間であると推定される。

    平成17年度マダガスカルと、南インドにおいて得られた試料から、大変に興味深い結果を得ることができた。この地域は、ゴンドワナ超大陸の一部で炭素の地殻とマントルのソースを研究するのに適当な地域である。マダガスカルのAntsirakambo鉱山でに採取されたカルクシリケイト質片麻岩とそれを貫く優白色花崗岩脈に含まれるグラファイトの結晶成長とその起源を明らかにするために、石墨結晶の微少炭素同位体の精密測定、異なった形態のグラファイト結晶のラマンスペクトルを測定した.カルクシリケイト片麻岩中のグラファイトはほぼ自形を示し,ラマンスペクトルは,オーダード結晶を示すスペクトルのみからなり,花崗岩脈中のグラファイトは自形を示す結晶の表面に細粒グラファイト結晶の集合体であるスケルタルグラファイトが見られ、ディスオーダースペクトルが特徴的に見られた.
    炭素同位体の結果から、カルクシリケイト片麻岩のグラファイトは-13.8‰,カルサイトは-10.3‰を示し,それぞれ非常に一定値を示した.この事は,グラファイトと共存するカルサイトが炭素同位体平衡の関係にあることを示し,同位体地質温度計を適用すると変成温度は,約760℃であると見積もることができた。また,産状から,それぞれの炭素の起源は,有機物(約-26‰)と海洋起源炭酸塩(約0‰)と考えられるが,広域的な石灰岩のスカルン化を伴う変成作用を受けて現在のグラファイト(-13.8‰),カルサイト(-10.3‰)に変化したと考えられる.花崗岩脈のスケルタルグラファイトだけからなる試料の炭素同位体比は-15.5‰,自形を示す結晶の表面にスケルタルグラファイトが成長しているものの全体の平均値は-12.9‰で、同位体的累帯構造の平衡関係を調べたところ,明瞭な累帯構造を示しコアからリムに向かって3.2‰も軽くなっていることが分かった.これらの炭素安定同位体比の結果から,自形グラファイトとスケルタルグラファイトは形成時期が異なり,スケルタルグラファイトは二次的に形成されたことを示唆している.
    ほかに、46次の南極調査に参加し、石墨試料の同位体研究を行い、堆積起源の変成岩では、南インドのデーターと比較できる結果を得て、東ゴンドワナの断片において、炭素から見た地殻の進化を議論できるところに進展し、近々、公表される予定である。
