Abstract Global-scale cycling of silicon through the biosphere, atmosphere, and hydrosphere has received much attention although, silicon cycling in the Earth's lithosphere remains poorly understood. As the products of internal heat and material exchange, igneous rocks preserve significant information of silicon migration through the lithosphere. Here we report silicon isotopic compositions of nine peraluminous granites from the Chinese Altai, which forms part of the Central Asian Orogenic Belt....

Abstract The granulite facies metapelite (khondalite) belt in the Trivandrum Block of southern India has been central to investigations on extreme crustal metamorphism associated with the final assembly of the Gondwana supercontinent during late Neoproterozoic-Cambrian. Here we investigate garnet-sillimanite-cordierite-spinel-bearing metapelites from this khondalite belt using state-of-the-art petrologic, mineral phase equilibria modelling, and coupled zircon and monazite U-Pb geochronology to c...

Abstract Silicate melt inclusions (MI) trapped in minerals provide direct tools to evaluate source characteristics and magma evolution including magma chamber processes. Here we present results from the study of MIs in basalts from the Western Ghats region of the Deccan Large Igneous Province (LIP) in India. The MIs in plagioclase and clinopyroxene phenocrysts were analyzed. The MIs exhibit post-entrapment modification by in situ crystal fractionation, chemical interaction with the host phenocry...

Abstract Pyroxenite is a relatively rare but important rock type of mafic-ultramafic series, and provides a useful tool to understand deep crustal and crust mantle processes. Here we present petrology, phase equilibrium modelling and P-T estimates, zircon U Pb geochronology and Hf isotopes on a recent find of garnet websterite from the Jambumalai hillock, Kolli-massif, southern India. The rock types in this location include metamorphosed orthopyroxenite, clinopyroxenite, garnet websterite and ga...

Abstract The Wutai complex is located within the Trans–North China Orogen (TNCO) which marks the collision zone between the Eastern and Western Blocks of the North China Craton (NCC). Here we investigate the timings and mechanisms of Precambrian arc building in Wutai from a suite of newly identified greenstone – felsic tuff – Banded Iron Formation (BIF) – phyllite sequence. Zircon grains from the felsic tuff layer intercalated within the greenstones provide robust constraints on the timing of BI...
Abstract The Hutouya Pb–Zn mining district in the Qiman Tagh region in NW China is a zoned skarn district with inner Fe–Sn–Cu–Co ores and outer Pb–Zn skarn mineralization. Temporal coincidence of 40Ar/39Ar plateau age of ore-stage phlogopite (226.9 ± 1.5 Ma) with weighted mean LA–ICP–MS U–Pb ages of zircons (230.3 ± 3.7 and 221.6 ± 1.3 Ma) and 40Ar/39Ar plateau ages of biotite (229.6 ± 2.3 and 224.7 ± 2.6 Ma) in the spatially-associated monzogranite strongly suggest a genetic relationship betwee...

Abstract The southwestern part of the South China Block is one of the major Sn, W and Cu metallogenic provinces related to Mesozoic granitoid suites. However, the genetic relationship between the magmatic petrogenesis and metallogeny is not well–constrained. Here we evaluate the petrogenesis of late Cretaceous granites and their link to regional metallogeny from the Dachang–Kunlunguan ore belt in the eastern part of the province. This belt includes biotite granites formed at ca. 98–97 Ma associa...

Abstract The Tianshan in China forms the southern part of the Central Asian Orogenic Belt (CAOB) and also hosts important polymetallic resources. Here we investigate the Huangtupo medium–size copper–zinc deposit, located in the central part of the Kalatag copper Polymetallic Belt with a view to evaluate the nature and genesis of the early Paleozoic volcanogenic massive sulfide (VMS) Cu—Zn deposits. This deposit is correlated to intermediate–felsic volcano–sedimentary sequences of the early Paleo...

Abstract Impact cratering is a dominant geological process in the Solar system and is one of the frontier themes in planetary research. Here we explore the possible dependency of surface gravity and crater geometry in the natural and theoretical prediction from scaling factor of crater diameter using morphometric analysis. Theoretical model predicts a negative correlation between final crater diameter (D fr ) and gravitational acceleration of the target body (g). In our study, an inner solar sys...
