The orthogneisses/granitoids and the supracrustal rocks underwent an early phase of high‐grade metamorphism at 3.30–3.28 Ga followed by low‐grade metamorphic events at 3.19–3.12 Ga and 3.02–2.96 Ga synchronous with the emplacement of younger felsic plutons such as the Mayurbhanj Granite (3.1 Ga; Misra et al., ).…”

The Central Indian Tectonic Zone (CITZ) is a Proterozoic suture along which the Northern and Southern Indian Blocks are inferred to have amalgamated forming the Greater Indian Landmass. In this study, we use the metamorphic and geochronological evolution of the Gangpur Schist Belt (GSB) and neighbouring crustal units to constrain crustal accretion processes associated with the amalgamation of the Northern and Southern Indian Blocks. The GSB sandwiched between the Bonai Granite pluton of the Singhbhum craton and granite gneisses of the Chhotanagpur Gneiss Complex (CGC) links the CITZ and the North Singhbhum Mobile Belt. New zircon age data constrain the emplacement of the Bonai Granite at 3,370 ± 10 Ma, while the magmatic protoliths of the Chhotanagpur gneisses were emplaced at c. 1.65 Ga. The sediments in the southern part of the Gangpur basin were derived from the Singhbhum craton, whereas those in the northern part were derived dominantly from the CGC. Sedimentation is estimated to have taken place between c. 1.65 and c. 1.45 Ga. The Upper Bonai/Darjing Group rocks of the basin underwent major metamorphic episodes at c. 1.56 and c. 1.45 Ga, while the Gangpur Group of rocks were metamorphosed at c. 1.45 and c. 0.97 Ga. Based on thermobarometric studies and zircon–monazite geochronology, we infer that the geological history of the GSB is similar to that of the North Singhbhum Mobile Belt with the Upper Bonai/Darjing and the Gangpur Groups being the westward extensions of the southern and northern domains of the North Singhbhum Mobile Belt respectively. We propose a three‐stage model of crustal accretion across the Singhbhum craton—GSB/North Singhbhum Mobile Belt—CGC contact. The magmatic protoliths of the Chhotanagpur Gneisses were emplaced at c. 1.65 Ga in an arc setting. The earliest accretion event at c. 1.56 Ga involved northward subduction and amalgamation of the Upper Bonai Group with the Singhbhum craton followed by accretion of the Gangpur Group with the Singhbhum craton–Upper Bonai Group composite at c. 1.45 Ga. Finally, continent–continent collision at c. 0.96 Ga led to the accretion of the CGC with the Singhbhum craton–Upper Bonai Group–Gangpur Group crustal units, synchronous with emplacement of pegmatitic granites. The geological events recorded in the GSB and other units of the CITZ only partially overlap with those in the Trans North China Orogen and the Capricorn Orogen of Western Australia, indicating that these suture zones are not correlatable.

“…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). Mukhopadhyay et al, 2014;Nelson et al, 2014). The volcanosedimentary succession occurring to the north of the Archaean Singhbhum nucleus has been inferred to constitute the Singhbhum mobile belt or North Singhbhum Mobile Belt (Saha, 1994;Gupta and Basu, 2000;Sengupta and Chattopadhyay, 2004;Dasgupta, 2004).…”

a b s t r a c tIn significant contrast to other cratonic blocks of India, the Singhbhum cratonic successions record continuous depositional record from the Palaeoarchaean to Mesoproterozoic. Although the sedimentary facies characteristics and mode of stratigraphic sequence building of the Dhanjori and Chaibasa Formations are well known, sedimentary geochemistry, provenance and tectonic milieu of deposition of these two formations are hitherto unknown. The current manuscript presents geochemical and Sm-Nd isotopic data from the Dhanjori and Chaibasa Formations for the first time and combine previous sedimentological data with the goal to expand the framework for understanding the depositional and tectonic setting of these two formations. The Sm-Nd isotopic data for the Chaibasa clastics is unambiguous with respect to provenance. Average ε Nd (t = 2.2 Ga) = −0.8 ± 1.0 and average Nd model age (TDM) = 2.51 ± 0.08 Ga with average 147 Sm/ 144 Nd ratios = 0.1114 ± 0.0041 for phyllites and quartzites indicate an extremely homogeneous source signature consistent with a late Archaean "juvenile" crustal provenance, possibly a dominantly upper crustal provenance. The Sm-Nd isotopic data from the older Dhanjori Formation also indicate broadly similar provenance as comparable lithologies in the younger Chaibasa Formation. Our Sm-Nd isotopic data is entirely consistent with the previous sedimentological data and confirms a terrestrial, riftdominated tectonic setting for the Dhanjori Formation (proximal sources, poorly mixed provenance) and a marginal marine to offshore setting for the more homogeneous Nd isotopic signature of the Chaibasa Formation (distal sources, well mixed provenance).

“…In India, Palaeoarchaean supracrustals occur in Dharwar, Bastar, and Singhbhum cratonic blocks (Mazumder & Eriksson, ; Naqvi & Rogers, ). In significant contrast to other Indian cratonic blocks, the Singhbhum cratonic block bears an almost continuous Palaeoarchaean to Mesoproterozoic geological record (Mukhopadhyay et al, ; Saha & Mazumder, ; Mazumder et al, ; Nelson, Bhattacharya, Thern, & Altermann, ; Ghosh, Ghosh, & Mukhopadhyay, ; Van Loon & De, ). Although researchers have inferred the Palaeoproterozoic volcano‐sedimentary processes on the Singhbhum cratonic block (De et al, ; ; Mazumder, ; Mazumder & Arima, ; Mazumder & van Loon, ), the Archaean geological history is largely unknown (cf.…”

Palaeoarchaean sedimentation and magmatic processes in the eastern Iron Ore Group, eastern India: A commentary

2019

The Singhbhum cratonic block, eastern India, unlike other Indian cratonic blocks, bears a continuous geological record from the Palaeoarchaean to Mesoproterozoic. The Palaeoarchaean Iron Ore Group of rocks are exposed along three distinct belts (the eastern, western, and southern) encircling the Singhbhum granitoids. The economic geological aspects of the BIF and the gold mineralization aspects of the quartz‐pebble conglomerates of the Eastern Iron Ore Group (EIOG) have been discussed by a number of authors. Komatiites and basalts of the EIOG have been studied by earlier authors. However, no effort has yet been made to infer the volcano‐sedimentary processes in the Eastern Iron Ore belt. This paper presents a brief overview of the sedimentation and magmatic processes in the EIOG belt. The EIOG sedimentary succession is characterized by a basal terrestrial to shallow marine deposits that progressively became deeper up section. The EIOG clastics bear carbonaceous matter. The basal terrestrial deposits (conglomerate‐sandstone association) of the EIOG provide a rare opportunity to undertake fluvial architectural analysis and may enable us to unlock the peculiarities of Palaeoarchaean fluvial systems.
