Magmatic and metamorphic history of Paleoarchean tonalite–trondhjemite–granodiorite (TTG) suite from the Singhbhum craton, eastern India
TL;DR: In this paper, texturally controlled dating of zircon from Paleoarchean tonalite-trondhjemite-granodiorites of the Older Metamorphic Tonalitic Gneisses and the Singhbhum Granite batholith (Phases I, II, and III) reveals a polycyclic evolution of the Archean crust.
Journal ArticleDOI
Lithostructural and chronological constraints for tectonic restoration of Proterozoic accretion in the Eastern Indian Precambrian shield
S. Rekha,Dewashish Upadhyay,Abhijit Bhattacharya,Ellen Kooijman,S. Goon,S. Mahato,Naresh Chandra Pant +6 more
TL;DR: In this article, the authors used laser ablation inductively coupled plasma mass spectrometry (LAMS) to estimate the ages of the Chottanagpur Gneiss Complex (CGC), the North Singhbhum Mobile Belt (NSMB) and the Singhbhem Craton (SC).
Journal ArticleDOI
Mesoproterozoic rift-related alkaline magmatism at Elchuru, Prakasam Alkaline Province, SE India
TL;DR: The Elchuru alkaline complex in the Prakasam igneous province represents one occurrence of several alkaline bodies within the craton-Eastern Ghats Belt contact zone in Peninsular India.
Journal ArticleDOI
Alkaline magmatism along the southeastern margin of the Indian shield: Implications for regional geodynamics and constraints on craton–Eastern Ghats Belt suturing
TL;DR: In this article, a plausible geodynamic model explaining the alkaline magmatism and its relationship to regional crustal evolution is proposed, which can be correlated to the breakup of the supercontinent Columbia and may have opened an ocean between eastern India and east Antarctica where the sedimentary sequences of the Eastern Ghats Province (EGP) were deposited between 1.4 and 1.2.
Journal ArticleDOI
Unraveling Sedimentary Provenance and Tectonothermal History of High‐Temperature Metapelites, Using Zircon and Monazite Chemistry: A Case Study from the Eastern Ghats Belt, India
TL;DR: The geochemical behavior of detrital zircon and monazite during granulite facies anatexis in metapelites from the Eastern Ghats Belt (EGB), India, is explored using U•Pb geochronology, Hf isotopes, and trace elements.
