“…Elsewhere in the CITZ, although Deshmukh et al. () have reported a Palaeoproterozoic (1.8–1.6 Ga) metamorphic event from the Mahakosal belt, this is temporally younger than that in the TNCO. Thus, the geological events that have shaped the Indian subcontinent, recorded in the CITZ between 1.65 and 0.9 Ga are conspicuously absent in the geochronological record of the TNCO.…”

“…The granulites occur as rafts, pods, and lenses within intensely tectonized felsic gneisses/composite gneisses (Acharyya & Roy, ; Bhowmik, Pal, Roy, & Pant, ; Bhowmik & Roy, ; Bhowmik et al., ; Roy & Prasad, ; Roy et al., ). The CITZ has a complex and protracted geological history involving Palaeoproterozoic subduction‐metamorphism and granite emplacement at 1.8–1.7 Ga (Deshmukh, Prabhakar, Bhattacharya, & Madhavan, ), granitoid magmatism at 1.60 Ga (Bhowmik, Wilde, & Bhandari, ; Bora, Kumar, Yi, Kim, & Lee, ), granulite facies metamorphism at 1.62–1.42 Ga (Bhandari, Pant, Bhowmik, & Goswami, ), and upper amphibolite to granulite/high‐ P granulite facies metamorphism at 1.06–0.94 Ga (Bhowmik, Wilde, Bhandari, Pal, & Pant, ; Chattopadhyay et al., ). At its eastern extremity, the CITZ separates into three thrust belts that divide the orogen into the Gangpur Schist Belt (GSB), the North Singhbhum Mobile Belt, and the Chhotanagpur Gneiss Complex (CGC).…”

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.

“…Appearance of andalusite, staurolite, garnet and cordierite in metapelites, preferentially near the southern margin, suggest that higher grade assemblages are restricted close to SNSF near the granite bodies. Recently, Deshmukh et al (2017) have studied the metamorphic evolution of pelitic schists and phyllites from northeast of Sidhi area, and concluded that peak metamorphism (M 2 ) occurred pre/syn-S 2 fabric (P~8 kbar and T~520°C), followed by post S 3 isothermal decompression (M 3 ) up to 2-3 kbar. Based on U-Th-total Pb monazite age dating methods, the authors have suggested the following age constraints for the different metamorphic stages: M 1 (prograde): 1.8-1.9 Ga, M 2 (peak): 1.65-1.75 Ga and M 3 (retrograde): 1.5-1.6 Ga.…”

The Central Indian Tectonic Zone, because of its critical position in the tectonic framework of East Gondwanaland, holds insights into our understanding of the assembly and dispersal of Columbia and Rodinia supercontinents through the growth of the Greater Indian Landmass. The tectonic zone, which is now a collage of different supracrustal and granulite‐gneiss belts, bears testimony to a multistage orogenic evolution from Late Palaeoproterozoic to Early Neoproterozoic time. In this contribution, the current status of orogenic evolution in the Central Indian Tectonic Zone has been reviewed using petrological and geochronological constraints from the Sausar Mobile Belt, its southernmost constituent. It reveals a three‐stage evolution leading to the growth of the Greater Indian Landmass: (a) c. 1.6–1.5‐Ga accretionary orogenesis produced the first nucleus of Greater India through the assembly of arc, back arc, and continental margins; (b) a phase of Middle Proterzoic extension led to the disintegration of the Proto‐Greater India; and (c) classical Himalayan‐style continental collision between 1.06 and 0.93 Ga finally stitched the North and South India blocks to produce the final configuration of the Greater Indian Landmass. It is argued that the Late Palaeoproterozoic to Early Mesoproterozoic orogenesis in India and former Gondwanaland and Laurentian fragments is a globally significant amalgamation event separate from the Columbia Supercontinent assembly.
