“…Documentation of Kumar et al (2017) is very important in the sense that during Neoarchean time, Singhbhum Craton was proximal to Pilbara and Kaapvaal Craton and therefore they altogether could define the Vaalbara LIP. Role of Neoarchean crust‐generation in the Singhbhum Craton has also been highlighted by Chaudhuri (2020) and this work also suggests a possible Pilbara connection of Singhbhum. The granite‐greenstone belts containing banded iron formation (BIF) of the Gorumahisani‐Badampahar‐Daitari Iron Ore Group (IOG) comprises an integral part of the Archean granite greenstone terranes and Proterozoic supracrustals of the Singhbhum Craton (Manikyamba et al, 2015; Mohanty, 2012).…”

Precambrian mafic magmatism is an important global episode which played a significant role in the crustal evolution. In India, Singhbhum Craton being the oldest craton, witnessed significant occurrences of Precambrian geological activity, marked by several episodes of volcanism, plutonism, sedimentation spanning from Palaeoarchean to Mesoproterozoic age. Here we present petrological and geochemical characteristics of Precambrian mafic volcanic rocks (occurring in western Iron Ore Group (IOG), Singhbhum Craton, eastern India) to evaluate their petrogenetic aspects, tectonic setting, and magma generation. The mafic volcanic rocks are porphyritic in nature with the phenocrysts of plagioclase and groundmass composed of clinopyroxene, plagioclase, ilmenite, and volcanic glass. These rocks are mostly tholeiitic, sometimes with a transitional behaviour towards calc‐alkaline nature and display basalt‐basaltic andesite affinity. These mafic volcanic rocks also preserve geochemical signatures (high Nb/U, Nb/La, [Nb/Th]pm ratios) in support of Nb‐enriched basalts and are classified as Nb‐enriched basalts (NEB; Nb > 7 ppm) and high‐Nb basalts (HNB; Nb > 20 ppm) on the basis of Nb concentrations and mantle normalized Nb/La ratios (>0.5). The NEBs and HNBs are marked by lesser magnitude of negative Nb anomalies with high (Nb/Th)pm, (Nb/La)pm, and Nb/U ratios as compared to normal arc basalts. Several major element oxides, trace elements, and selected element ratios (like SiO2, CaO/Al2O3, Y, V/Cr, Zr/Nb, and ∑REE) show systematic variations with MgO which suggests role of magmatic fractionation. Chondrite‐normalized REE patterns for NEB and HNB rocks exhibit uniform LREE enrichment with distinct Eu negative anomalies while primitive mantle‐normalized incompatible trace element patterns reflect enrichment in LILE and LREE with prominent Nb‐Ta anomalies. Different HFSE ratios corroborate a subduction related setting for magma generation formed by ∼10%–20% melting in the domain of garnet lherzolite. Relative enrichment of LILE and LREE with depleted HFSE characteristics attest a garnet‐bearing mantle source and melt extraction with garnet in the residue. Geochemical signatures suggest that the genesis of NEB and HNB is attributable to slab‐melting and wedge hybridization processes during matured stages of subduction. Selected incompatible trace element ratios for the studied mafic volcanic rocks invoke an enriched (EM1‐EM2 type) mantle source and unequivocally suggest effects of continental crustal assimilation of the parent magma. Liquid immiscibility has played an important role as a differentiation mechanism leading to presence of high and low FeO types. The IOG mafic volcanic rocks preserve distinct geochemical signatures of matured stage of subduction, slab melting, crustal contamination and magma generation at an Archean ocean–continent convergent margin setting.

“…The Singhbhum Craton of eastern India (Figure 2) preserves a long stratigraphic history of crustal evolution from Palaeoarchean to terminal Mesoproterozoic (summarized in Table 2; see for reviews Chaudhuri, 2020; Mazumdar, 1996; Mazumder, Eriksson et al,2012; Misra, 2006; Mukhopadhyay, 2001; Mukhopadhyay et al, 2008, Mukhopadhyay, Crowley et al, 2014; Mukhopadhyay & Matin, 2020; Olierook et al, 2019; Sarkar, Gupta, & Basu, 1992; Saha, 1994; Upadhyay et al, 2014). The core of the craton comprises Palaeo‐Mesoarchean TTG plutons (the Older Metamorphic Tonalitic Gneiss, known as the Older Metamorphic Tonalite Gneiss (OMTG), and Singhbhum‐Bonai Granites, known as the SBG), BIF‐bearing greenstone belts collectively termed as the Iron Ore Group (IOG), metasedimentary and metavolcanic enclaves of the Older Metamorphic Group (OMG; Hofmann & Mazumder, 2015; Manikyamba et al, 2015; Saha, 1994) and the Mesoarchean siliciclastic successions (Mahagiri‐Keonjhar‐Mankharchua quartzites; De, 2019; Ghosh, De, & Mukhopadhyay, 2016; Mukhopadhyay, Crowley et al, 2014).…”

Detrital zircon U–Pb LA‐ICPMS ages from the Kolhan Group, Singhbhum Craton, eastern India: Implications for terminal Mesoproterozoic palaeogeography between Columbia and Rodinia along the Central Indian Tectonic Zone

et al. 2020

The Kolhan Group in the Singhbhum Craton of eastern India is a passive margin siliciclastic shelf to deep‐water carbonate ramp platform succession. It occupies a unique position in respect of the Central Indian Tectonic Zone (CITZ), widely considered as the suture joining the northern and southern Indian cratonic blocks at the time of amalgamation of the Mesoproterozoic supercontinent Columbia. The Kolhan succession is closely comparable to other Late Proterozoic ‘Purana’ successions of India including the siliciclastic‐carbonate Suasar Group from the central part of the CITZ. We report here the first U–Pb detrital zircon ages from the Kolhan Group. The youngest age population obtained from basal siliciclastics suggests it is not older than ca. 1,158 Ma. The absence of any concordant detrital zircon <1,000 Ma which is well represented in the adjoining Singhbhum Shear Zone and CITZ extensions, suggests that the sedimentation took place prior to ca. 1,000 Ma. The Kolhan Group, therefore, records an extensional event between two major episodes of supercontinent assembly (i.e., Columbia and Rodinia). A similar motif of extension and passive margin sedimentation across Mesoproterozoic Peninsular India together with the widespread Mesoproterozoic lamproite and kimberlite emplacement event suggests an episode of extension and major basin development across the Indian Shield in between the two supercontinent amalgamation cycles of Columbia and Rodinia.

“…Crustal formation in the craton possibly started as early as in the Hadean and got subsequently remobilized till the end of the Palaeoarchean. It is characterized by extensive occurrences of Palaeoarchean to Mesoarchean TTG crust (Dey et al, 2017; Nelson et al, 2014; Pandey et al, 2019; Upadhyay et al, 2014), and almost complete record of crustal formation from Palaeoarchean to Palaeoproterozoic can be seen preserved here (Chaudhuri, 2020; Dey et al, 2019; Dey & Moyen, 2020). This includes the oldest granitoids consisting of gneisses that belong to the Older Metamorphic Tonalite Gneiss (OMTG) suite, which is currently being referred to as Champua suite (Dey et al, 2017).…”

Possible occurrence of Palaeoarchean ferropicrite cumulates and ferrobasalts in the Jojohatu area of North Singhbhum Craton, eastern India: Evidence for a mantle plume source

et al. 2021

An occurrence of Palaeoarchaean ferropicrite cumulates and ferrobasalts is being reported from the Jojohatu area of the Iron Ore Group (IOG) greenstone belt, which is situated in the northern part of the Singhbhum Craton (eastern India). The ferropicrite cumulates contain serpentine and clinopyroxene as major constituents and spinel, magnetite, and ilmenite as accessories. Their bulk rock chemistry exhibits an extremely high amount of FeOT (19.0–20.8 wt%) and MgO (22.0–23.9 wt%) and quite low Al2O3 (4.5–5.2 wt%) and Na2O + K2O (<1.0 wt%), thus making them as one of the most Fe‐rich ferropicrite cumulates in the world. They are also characterized by high contents of compatible trace elements (Ni: 986–1,470 ppm; Cr: 990–1,256 ppm) and moderate TiO2 (1.5–1.7 wt%), Nb (15–18 ppm), and Zr (82–90 ppm). These cumulates are possibly formed due to accumulation of olivine from the ferrobasaltic melts. In comparison, ferrobasalts consisting of plagioclase, pyroxene, and opaques are alkaline in nature. Some of the plagioclase and pyroxene grains have shown a signature of metasomatic alteration, which resulted into formation of secondary minerals such as epidote, chlorite, and hornblende. They exhibit relatively low contents of FeOT (14.6–18.4 wt%), MgO (8.4–10.8 wt%), Ni (32–122 ppm), and Cr (41–131 ppm) than the ferropicrite cumulates, while TiO2 (2.9–4.1 wt%), Nb (42–61 ppm), and Zr (216–318 ppm) contents are higher. Incompatible elemental patterns and their ratios, as well as Zr/Y versus Nb/Y plot, indicate their ocean island basalts (OIB) affinity and genesis from a hot mantle plume, having mantle potential temperature of about 1,600°C and pressure of 3.5–5 GPa. Considerably low CaO (3.00–7.16 wt%) and FeO/MgO and CaO/MgO systematics indicate that the primary source of the basaltic melt could be pyroxenite. These volcanic occurrences possibly represent remnants of the OIB formed during the Palaeoarchean in the eastern part of the Indian shield.
