Origin of Late Palaeoproterozoic Great Vindhyan basin of North Indian shield: Geochemical evidence from mafic volcanic rocks

Precambrian crustal evolution of Peninsular India: A 3.0 billion year odyssey

“…The observed volcaniclastic units, faults and paleoseismic sedimentary deformation in the lower part of the Vindhyan section support the rift origin of the basin but is also the source of some controversy (Bose et al, 2001). In a recent contribution, Raza et al (2009) looked at the geochemistry of the basal volcanic sequence (Khairmalia and Jungel) and linked the formation of the Vindhyan Basin beginning at $1800 Ma to collisional events in the AravalliDelhi Fold belt and the Central Indian Suture (CIS).…”

Geochemistry of lower Vindhyan clastic sedimentary rocks of Northwestern Indian shield: Implications for composition and weathering history of Proterozoic continental crust

“…In the following period the movements probably related to fagging phase of Aravalli orogeny may have uplifted the terrain further in the west with some old crust exposures to high altitude and created a more extreme relief. As a result, older granitoids of BGC uplifted and exposed to produce debris for the basin developed in front of newly formed Aravalli belt (Raza and Casshyap, 1996;Chakrabarti et al, 2007;Raza et al, 2009). Hence, it is likely that the increase in elevation caused change of provenance and increased the amount of recycled sediments into the sedimentary basin.…”

Common Reflection Surface Stack Imaging of the Proterozoic Chambal Valley Vindhyan Basin and Its Boundary Fault in the Northwest India: Constraints on Crustal Evolution and Basin Formation

“…It suggests that the lower Vindhyans are not directly sitting over granitic basement but underlain by volcanics. Further, the Jungel and Khairmalia volcanics, with a close affinity toward either continental flood basalts or oceanic island arc basalts, are identified on the western and southern margins of the Vindhyan basin (Raza et al, 2009). These volcanics were found to have formed in a rift environment and are located below the Vindhyan…”

“…The Deccan protocontinent is a collective crustal block of the Dharwar, Baster, and Singhbum cratons. The Paleoproterozoic Satpura and Aravalli orogenic belts were formed during the collisional episodes (Chakrabarti et al, 2007;Raza et al, 2009;Vijaya Rao & Reddy, 2002). There is no consensus regarding the evolution of the basin.…”
