“…Peninsular India comprises five cratonic blocks (Dharwar, Singhbhum, Bastar, Bundelkhand and Aravalli) bordered by mobile belts (Eastern Ghats Mobile Belt, Southern Granulite Terrain and Central Indian Tectonic Zone) (Fig. 1) (Jain et al 2020;Jayananda et al 2020b). The Indian cratons have distinct evolutionary histories marked by multiple cycles of basin formation, sedimentation, magmatism, deformation, metamorphism and mineralization (Sarkar & Gupta 2012;Jain et al 2020;Jayananda et al 2020b).…”

Granitoids form the dominant component of Archean cratons. They are generated by partial melting of diverse crustal and mantle sources and subsequent differentiation of the primary magmas, and are formed through a variety of geodynamic processes. Granitoids, therefore, are important archives for early Earth lithospheric evolution. Peninsular India comprises five cratonic blocks bordered by mobile belts. The cratons that stabilized during the Paleoarchean–Mesoarchean (Singhbhum and Western Dharwar) recorded mostly diapirism or sagduction tectonics. Conversely, cratons that stabilized during the late Neoarchean (Eastern Dharwar, Bundelkhand, Bastar and Aravalli) show evidence consistent with terrane accretion–collision in a convergent setting. Thus, the Indian cratons provide testimony to a transition from a dominantly pre-plate tectonic regime in the Paleoarchean–Mesoarchean to a plate-tectonic-like regime in the late Neoarchean. Despite this diversity, all five cratons had a similar petrological evolution with a long period (250–850 myr) of episodic tonalite–trondhjemite–granodiorite (TTG) magmatism followed by a shorter period (30–100 myr) of granitoid diversification (sanukitoid, K-rich anatectic granite and A-type granite) with signatures of input from both mantle and crust. The contributions of this Special Publication cover diverse granitoid-related themes, highlighting the potential of Indian cratons in addressing global issues of Archean crustal evolution.

“…There has been widespread granitic magmatism in the Indian shield, as seen in the Aravalli, Bundelkhand, Dharwar, and Bastar cratons during the Archean-Proterozoic boundary (Jayananda et al, 2020). The Bastar Craton (Figure 1), with abundant Archean-Proterozoic supracrustals and granitoids, hold critical clues reflecting the significant changes that occurred during this period (Khanna et al, 2019;Mondal et al, 2019;Santosh et al, 2020).…”

Petrogenesis of the Kanker Granites From the Bastar Craton: Implications for Crustal Growth and Evolution During the Archean-Proterozoic Transition

et al. 2020

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.

“…Indian Shield is characterized by widespread granitic magmatism, as evidenced from the Aravalli, Bundelkhand, Dharwar, and Bastar cratons during the Archean-Proterozoic boundary. The rocks from Dharwar craton have been studied in detail for their field relationships, geochemical and isotopic characterization, petrogenesis, and geochronology (Jayananda et al, 2020). The Indian subcontinent evolved through the amalgamation of Northern and Southern Indian cratonic blocks (NIB and SIB) along the Central Indian Tectonic Zone (CITZ), trending east-west for ~1600 Km (Naqvi and Rogers, 1987;Rogers and Gird, 1997;Stein et al, 2004;Bhowmik, et al, 2012: Fig.…”

Geochemistry and petrogenesis of Proterozoic granitoids from Central Indian Tectonic Zone (CITZ): elemental and isotopic constraints

et al. 2022

The Central Indian Tectonic Zone (CITZ) is major E-W trending suture zone between Northern and Southern Indian crustal blocks. The southern portion of the CITZ comprises three lithotectonic units: Tirodi Gneissic Complex (TGC), Sausar Mobile Belt (SMB) and Bhandara-Balaghat Granulite Belt (BBGB). Elemental and isotopic data are used to constrain the genesis of granitoids and their protoliths, which may help us to understand the Proterozoic crustal evolution in CITZ. Geochemical and isotopic results are consistent with previous studies that these granitoid plutons are linked to the felsic magmatism of the Columbian crustal assembly in India, North America and North China. Granitoids varies from tonalite to granite, alkalic to calcic, metaluminous to peraluminous composition. Normalized elemental ratios of La/Sm, La/Yb, La/Lu, and Gd/Yb depict variable LREE enrichments and varying degrees of partial melting of heterogeneous crustal/lithospheric sources. The studied rocks are characterized by positive anomalies for Pb and negative anomalies for Nb, Sr, P, Ti, which indicate the influence of subduction-zone fluids in the source regions. Negative anomalies for K, Sr, and Ti for SMB and BBGB granitoids may also be attributed to K-feldspar, plagioclase, and Fe-Ti oxide fractionation. However, TGC porphyritic leucogranites display K, Ba and Eu positive anomalies, probably related to the accumulation of K-feldspar phenocrysts. Nd-Sr data presents initial ratios of 143 Nd/ 144 Nd t=1.6 Ga ranges between 0.509961 and 0.510300; εNd t=1.6 Ga ranges from -5.3 to -11.9 with TDM ages ranging from 2.20 to 2.78Ga for TGC granitoid. The ratios of 143 Nd/ 144 Nd t=1.6 Ga ranges between 0.510232 and 0.510985; εNd t=1.6 Ga ranges from +0.2 to +8.2 and TDM ages varies from 1.5 to 3.0 Ga. The initial 87 Sr/ 86 Sr t=1.6 Ga ratios ranges between 0.699834 and 0.797151 for SMB granitoid. However, BBGB granitoids show the ratios of 143 Nd/ 144 Nd t=1.6 Ga ranges between 0.509752-and 0.510910; εNd t=1.6 Ga ranges from +6.7 to -16, and TDM ages range from 1.51 to 3.29 Ga. The initial 87 Sr/ 86 Sr (t=1.6 Ga) ratios varies between 0.705096 and 0.717440. These ranges of εNd (t) and TDM values possibly indicate their derivation from enriched and heterogeneous crustal/lithospheric sources, and minor components from depleted lithospheric sources.
