ca. 2.1 Ga Mahakoshal Supracrustal Belt: An allochthonous terrain in Central India Tectonic Zone

TC Khanna, DVS Rao, VVS Sai, M Satyanarayanan - Lithos, 2020 - Elsevier
Back-arc magmatism is perhaps extremely rare in a Paleoproterozoic mobile tectonic
regime. The present study provides a detailed account on the petrogenesis of basalts that
are interleaved with marine sedimentary rocks in the Agori Formation, which overlies the
Chitrangi Formation in the~ 2.1 Ga Mahakoshal supracrustal belt within the Central India
Tectonic Zone. The basalts are sub alkaline, tholeiitic in nature. They have moderate
concentrations of TiO 2 (~ 0.9 wt%), Nb (2.6–5.2 ppm), and Zr (59–105 ppm), Zr/Nb (18–24) …
