∼2.1 Ga intraoceanic magmatism in the Central India Tectonic Zone: Constraints from the petrogenesis of ferropicrites in the Mahakoshal supracrustal belt

The preserved pillow structures imply that magmatism took place in an ocean basin. Therefore, we argue for the existence of a proto-ocean prior to the amalgamation of the northern cratonic block consisting of Aravalli and Bundelkhand proto-continents, and the southern cratonic block consisting of Singhbhum, Bastar and Dharwar proto-continents, which were still adrift at ∼2.1 Ga.
