Mineralogy, geochemistry, and genesis of co-genetic granite-pegmatite-hosted rare metal and rare earth deposits of the Kawadgaon area, Bastar craton, Central India
Co-genetic pegmatites associated with the granite of the Kawadgaon area in the Bastar craton, Central India, contain a wide range of ore minerals of Nb, Ta, Be, Sn, Zr, Ti, and REE, includingExpand
The Bastar craton, central India: A window to Archean – Paleoproterozoic crustal evolution
Abstract The Bastar craton in central India, surrounded by cratonic blocks and Paleoproterozoic to Neoproterozoic orogenic belts, is a window to investigate the Archean-Paleoproterozoic crustalExpand
Petrography and Geochemistry of Ore-Bearing Granites and Pegmatites from Bastar Craton, Central India
The granite-pegmatite systems of the Bastar craton, central India host polymetallic Nb,Ta,Sn,Be,Li ore deposits, which are genetically related to various granitic bodies locally called the Paliam-,Expand
Age-integrated tectonic model revealing the deep-to shallow-crustal evolution of Eastern Ghats Orogenic Belt, India
The Eastern Ghats Belt (EGB), India is a Proterozoic orogen which co-evolved with its Precambrian neighbors (East Antarctica, Australia, China and parts of Laurentia) during several supercontinentalExpand
Dating of Columbite-tantalite and Monazite from Pegmatites of the Kawadgaon–Challanpara Area, Bastar Craton, Central India
The results of geochronological studies on columbite-tantalite and monazite from the rare metal pegmatites of the Kawadgaon–Challanpara area in Bastar craton, central India are presented.Expand
Age-integrated tectonic evolution across the orogen-craton boundary: Age zonation and shallow- to deep crustal participation during Late Cambrian cratonisation of Eastern Ghats Belts, India
Abstract The Eastern Ghats Belt (EGB) is an orogenic belt which is known to evolve through Proterozoic time before cratonisation with Proto-India and holds an important key to the reconstruction ofExpand
Zircon U–Pb SHRIMP and monazite EPMA U–Th–total Pb geochronology of granulites of the western boundary, Eastern Ghats Belt, India: a new possibility for Neoproterozoic exhumation history
Abstract We present detailed and high-precision geochronological data on granulites occurring along the western boundary of the Eastern Ghats Belt, India. Age data on systematically sampled rocksExpand
Restoration of Late Neoarchean–Early Cambrian tectonics in the Rengali orogen and its environs (eastern India): The Antarctic connection
Abstract Geological mapping and P–T path reconstructions are combined with monazite chemical age and Secondary Ion Mass Spectrometric (SIMS) U–Pb zircon age determinations to identify crustal domainsExpand
Chapter 11 Palaeoproterozoic supracrustals of the Bastar Craton: Dongargarh Supergroup and Sausar Group
Abstract The Bastar Craton of India is composed of Archaean nuclei of tonalite–trondhjemite–granodiorite gneisses, enveloped by an older granite–greenstone belt (>3000 Ma) with banded iron formationExpand
Precambrian continent assembly and dispersal events of South Indian and East Antarctic Shields
An Archaean continent ‘SIWA’, an acronym for South India–Western Australia, comprising the Bastar–Dharwar craton, the Yilgarn craton, the Napier Complex, and the Vestfold Hills has been identifiedExpand
