In this study, we investigate the geological significance and antiquity of lower crustal granulite facies metamorphism from Rengali Domain, which lies in between Singhbhum Craton north Eastern Ghats Mobile Belt south. Petrographic, mineral compositional, metamorphic reaction history geothermobarometric studies two representative metapelite samples reveal widespread biotite melting at peak conditions 7.8 ± 0.13 kbar, 849 31 °C subsequent melt extraction, producing a mixture residual...
Abstract Magmatic Ni-Cu-platinum group element (PGE)-Te mineralization in the Gondpipri mafic-ultramafic layered intrusion of ca. 3323 ± 74 Ma age, western Bastar craton, central India, is one most prospective exploration targets for magmatic sulfides India. The divided into two distinct groups rocks based on their potential, which include (1) mineralized gabbro and pyroxenite (2) a barren olivine intrusion. host show Cu + Ni concentrations up to 5,000 ppm with Cu/Ni ratio <1 all PGE...
Abstract In this study, we constrain the petrogenesis and U–Pb zircon age of a newly discovered alkaline complex, christened Chaitma Alkaline Complex at southern margin Central Indian Tectonic Zone in central India. The comprises syenites gabbros, emplaced coevally, show features consistent with magma mixing. Geochemically, are potassic–ultrapotassic (K 2 O/Na O: 0.79–3.42), contain high Ba ( c. 800–2700 ppm) Sr 1400–3200 ppm). They enrichment light rare earth elements (LREEs) relative to...
Gahnite occurs in diverse rock types and metamorphosed mineral deposits. The gahnite geochemistry is being used as an exploration tool for zinc sulfide In the present study, of associated minerals viz. sphalerite, garnet, sillimanite, staurolite, anthophyllite, biotite, ilmenite, chlorite, their petrography have been studying genesis, metamorphic evolution, deposit characterization, significance seven Palaeoproterozoic volcanogenic massive sulfides (VMS) deposits Betul belt Central Indian...
Abstract The Proterozoic Chimalpahad Anorthosite Complex (CAC) is a deformed and dismembered complex in South India comprising of anorthosite-leucogabbro-gabbro-ultramafic rocks. It located the Nellore-Khammam Schist Belt (NKSB) within contact zone between Eastern Dharwar Craton (EDC) Ghats (EGB). chromitites occur as small lensoidal bodies ultramafic Presence micrometric inclusions iridium-like platinum-group minerals (IPGM), such laurite (RuS2), erlichmanite (OsS2), irarsite (IrAsS),...
Abstract This study reports on two lamprophyre dykes from the Rapuru area along margin of Eastern Dharwar Craton (EDC) and Nellore Schist Belt (NSB). The (RL) are situated southern extension Prakassam Alkaline Province (PAP). RL deformed, yet still preserve a porphyritic–panidiomorphic texture, with mica phenocrysts, amphibole feldspars in groundmass. Geochemically, have low Mg# (0.28–0.37), Ni (30–60 ppm) Cr (119–228 concentrations that indicate their evolved nature, such as for other...
