“…These 2.37 Ga giant radiating dyke swarm that extend across Southern India mark the closer proximity between the Eastern Dharwar and Bastar cratons prior to the 2.37Ga rifting event, and probably were part of a poorly constrained super continent that connects both cratons. Similarities in the sedimentation histories in relation with the super‐continent breakup events have also been noted in both cratons (Liao et al, 2019; Saha & Patranabis‐Deb, 2014).…”

“…The greenstone belts of Bastar and Eastern Dharwar cratons are mostly composed of shallow mantle (MORB related) volcanic sequences (Figure 6b), whereas the greenstone belts of adjacent Western Dharwar craton are markedly different due to the presence of high temperature komatiite‐tholeiite dominated greenstone associations (Saha et al, 2015). Liao et al (2019), correlated the 2.37 Ga Bhanupratappur dyke swarms in the Bastar craton and similar‐aged dyke swarms from the Eastern Dharwar craton. These 2.37 Ga giant radiating dyke swarm that extend across Southern India mark the closer proximity between the Eastern Dharwar and Bastar cratons prior to the 2.37Ga rifting event, and probably were part of a poorly constrained super continent that connects both cratons.…”

“…Major magmatic and metamorphic events at ~1.6 Ga and ~1.4 Ga are also correlated with the formation of accretionary orogens in the Central Indian Tectonic Zone (CITZ) (Roy & Prasad, 2003). The boninitic dykes of Bastar craton and NE Dharwar craton (2.3 Ga; Liao et al, 2019) are considered part of a poorly constrained supercontinent at 2.3 Ga. The Chhattisgarh Basin, in the northern segment, constitutes a great proposition of Meso‐Proterozoic sedimentary units.…”

“…In the present study, the PGE concentration of Boradih intrusion is evaluated to determine its mineralization potential and petrogenesis. Moreover, we discuss aspects of mantle melting, oxidation conditions, and tectonic settings of SGB and the greenstone belts of the Eastern Dharwar craton, to elucidate the premise that the Bastar and Eastern Dharwar cratons were together, as part of an ancient supercontinent, prior to 2.3 Ga (Liao et al, 2019).…”

The Sonakhan greenstone belt (SGB), located in the north‐eastern Bastar craton of the Indian shield, comprises mafic‐ultramafic and volcanic‐intrusive sequences in the lower stratigraphic units. We investigate the Platinum‐group element (PGE) relations of Boradih intrusion of the SGB to evaluate its tectono‐magmatic evolution. The chondrite‐normalized PGE patterns of boninitic cumulate rocks exhibit higher abundance of Palladium group PGEs (∑PPGE = 292–496 ppb) relative to the Iridium group PGEs (∑IPGE = 32–52 ppb) along with variable Au concentrations (51.34–718.05 ppb). The PGE concentrations are attributed to a boninitic parental melt, where the IPGEs in the source possibly partitioned into a monosulphide solid solution. The Cu (22–80 ppm), elevated Pt (22–238 ppb), and Pd (31–377 ppb) concentrations indicate Pt and Pd have partitioned into a semi‐metal rich melt during the later stages of crystallization. The geochemical characteristics of the basalts and ultramafic cumulates of the SGB indicate a supra‐subduction zone tectonic setting for its formation. Similar geochemical and litho‐tectonic correlations are also noticed between the SGB of Bastar craton and greenstone belts of the Eastern Dharwar craton of south India. The SGB (V/Yb =146 ± 25) and greenstone belts of Eastern Dharwar craton (V/Yb = 134 ± 52) record similar oxidation conditions of Phanerozoic subduction zones. Accordingly, we propose magmatic as well as tectonic correlations are possible for the Archean‐Palaeoproterozoic Bastar and Eastern Dharwar cratons.

“…The Bastar Craton remains one of the prominent cratons in the Indian shield, mainly due to the mineralization, proximity to the CITZ and imprints of supercontinental cycles (Pandit and Panigrahi, 2012;Santosh et al, 2018;Liao et al, 2019). In addition to the Kanker, Dongargarh and Malanjkhand are the two other major Archean-Proterozoic granitic plutons.…”

Archean-Proterozoic boundary represents a significant transitional phase in the Earth's history. Bastar Craton is one of the major Archean cratons in the Indian subcontinent with voluminous granites, supracrustal rocks, and tectonic belts. Malanjkhand, Dongargarh, and Kanker are the three major granitic plutons emplaced during the Archean-Proterozoic transition in the Bastar Craton, and this study is confined to the granites of Kanker pluton. Based on geochemical systematics, the Kanker granites are classified into sanukitoids, biotite and two-mica granites, and hybrid granites. The compositional diversity of the Kanker granites is attributed to two end-member sources, i.e., the enriched mantle and an older felsic crust, and the interactions between them. The sanukitoids were derived from an enriched mantle source that was metasomatized by the subducted sediments. Heat supplied by the sanukitoid magmas induced the crustal melting to form the biotite and two-mica granites. The interaction between these two mutually end-member sources, i.e., the enriched mantle and an older felsic crust, resulted in the formation of hybrid granites. The evolution of the Kanker granites can be accounted for a transitional geodynamic environment, involving subduction, and collisional tectonics during the Archean-Proterozoic transition.

Reverse fractionation modeling considering energy-constrained assimilation-fractional crystallization is performed to estimate primary magma compositions, degree of crustal contamination, pressure–temperature of equilibrium with mantle, and potential temperatures for the origin of the Paleoproterozoic (~ 2.37–1.88 Ga) basaltic dikes in central and eastern Dharwar Craton and sills and volcanics in the adjoining Cuddapah Basin, southern India. Mineral thermobarometry indicates that the dikes crystallized at upper crustal conditions (~ 1–6 kbar/ ~ 1120–1210 °C). Hence, the reverse fractionation calculations are performed at low pressures by adding olivine + plagioclase + clinopyroxene, olivine + plagioclase and only olivine in equilibrium with melt, and simultaneously subtracting an upper crustal partial melt in small steps until the melt is multiply saturated with lherzolite at a high pressure. The results indicate that the basalts are 5–30% contaminated, and their enriched light rare earth element (REE) patterns can be attributed to upper crustal assimilation. The upper crust was pre-heated to 665–808 °C during dike emplacement. The primary magmas of all basalts were last equilibrated with spinel lherzolite at 10–16.5 kbar/1291–1366 °C, and they resemble pooled polybaric incremental melts generated along a ~ 1450 °C adiabat. The estimated mantle potential temperatures (1293–1515 °C) are similar to Paleoproterozoic ambient mantle temperatures. All basalts and their primary magmas show lower chondrite-normalized DyN/YbN ratios than the plume-derived mid-Proterozoic Mackenzie dikes of Canadian Shield, and the primary magmas show flat REE patterns indicating spinel lherzolite melting. The low estimated potential temperatures, low DyN/YbN ratios, and a spinel-bearing mantle source are at odds with an origin of the basalts from mantle plumes.
