Paleoarchean partial convective overturn in the Singhbhum Craton, Eastern India

Restoration of Late Neoarchean–Early Cambrian tectonics in the Rengali orogen and its environs (eastern India): The Antarctic connection

“…32 supracrustal belt, in all probability, correspond to detrital zircon and monazite grains derived from the neighboring Bastar (2.0-2.6 Ga; this study) and Singhbhum Cratons (dominantly 3.6-2.9 Ga, Prabhakar and Bhattacharya, 2013, and references there in), and the Grenvillian-age EGGB (Aftallion et al, 1988;Biswal et al, 2007;Mezger and Cosca, 1999; this study) and the GSB (1.0-0.9 Ga; this study) metamorphic belts.…”

“…in the Singhbhum Craton (Basu et al, 1996;Sharma et al, 1994;Mishra et al, 1999;Prabhakar, 2013;Prabhakar and Bhattacharya, 2013), and in the Meso/Early Neoproterozoic crustal domains of NSMB and CGC (Fig. 14).…”

Geochemical and Sm–Nd isotopic characteristics of the Late Archaean-Palaeoproterozoic Dhanjori and Chaibasa metasedimentary rocks, Singhbhum craton, E. India: Implications for provenance, and contemporary basin tectonics

“…Interestingly, a subduction-accretion complex in the Singhbhum during the Palaeo-Mesoarchaean time has been inferred by several authors (Saha et al, 2004;Mukhopadhyay et al, 2012; see also Prabhakar andBhattacharya, 2013, Chaudhuri et al, 2015). Based on their Sm-Nd isotope data, Saha et al (2004) have inferred that the provenance of the late Archaean Birtola sandstone (see Mazumder et al, 2012a for discussion) formed in an island arc setting.…”

“…1) is among one of the few Precambrian terrains in the world that reportedly records sedimentation and volcanism in a changing tectonic scenario ranging from Palaeo-archaean to Mesoproterozoic (Saha, 1994;Mazumder et al, 2000Mazumder et al, , 2012aMukhopadhyay, 2001;Mazumder, 2005;Eriksson et al, 2006;Prabhakar and Bhattacharya, 2013; Mukhopadhyay, 2001). The Singhbhum granitoid and the eastern (E), western (W) and southern (S) Iron Ore Group of rocks constitute the Archaean Singhbhum nucleus (see Mukhopadhyay, 2001 andMazumder et al, 2012 for details).…”

Uraniferous paleoplacers of the Mesoarchean Mahagiri Quartzite, Singhbhum craton, India: Depositional controls, nature and source of >3.0Ga detrital uraninites

“…The age of the successions within the NSMB is yet to be well constrained. The ages of metamorphism, mineralization and granite emplacement within NSMB suggest sedimentation event between 2.7 to 2.1 Ga, deformation and mineralization events from 1.9 Ga to 1.0 Ga with a peak of deformation and mineralization at ~1.6 Ga (Mukhopadhyay, 2001;Gupta and Basu, 2000;Mahato et al, 2008;Mazumdar 2012;Pal et al, 2011;Pal and Rhede 2013;Prabhakar and Bhattacharya 2013;De et al, 2014).…”
