The Proterozoic felsic and mafic magmatism in India in varied tectonic settings is reviewed and discussed based on available geological, geochemical, and geochronological constraints. Neoarchean-Paleoproterozoic magmatism, as discrete volcano-plutonic complexes and Large Igneous Provinces (LIPs) in the Bastar, Singhbhum and Dharwar cratons and associated mobile belts are also included. Paleoproterozoic magmatism also contributed to the geodynamics of Himalaya. Meso- to Neoproterozoic magmatism comprises kimberlites and lamproites in the Bastar and Dharwar cratons. Neoproterozoic magmatic rocks chiefly constitute the Aravalli-Delhi mobile belts. Mantle-derived magmas, mainly as mafic to hybrid enclaves and syn-plutonic dykes, have contributed significantly in the evolution of calc-alkaline, metaluminous (I-type) to peraluminous (S-type) granites formed in subduction to post-collision tectonic zones. Anorogenic (A-type) granites are commonly reported in post-collision to rift environments. As a whole Proterozoic mafic-felsic magmatism contributed greatly in the crustal architecture and evolution of Indian subcontinent that are correlatable with the construction and break-up of Columbia and Rodinia supercontinents.
