The Proterozoic Cuddapah basin of Southern India, with an aerial extent of 44,500 km2, is one of the largest sedimentary basins in the world that witnessed significant events of magmatism during its evolution. Initiated around 2.1–2.0 Ga, the basin preserves a protracted history of sedimentation, magmatism and tectonism from Paleo to Neoproterozoic. Through this paper we explicate the Paleoproterozoic ultramafic-mafic-felsic magmatic events that are contemporaneous with the sedimentation of Cuddapah Supergroup. The~ 1.9 Ga ultramafic-mafic sills, along with basic and felsic volcanics and the interbedded tuffaceous rocks are stratigraphically confined to the Cuddapah Supergroup; that hosts substantial sedimentary sequence in the Cuddapah basin of Eastern Dharwar Craton. We provide a chronological illustration of Paleoproterozoic ultramafic-mafic-felsic magmatic events with details of available geochronological ages; their location and position in the stratigraphic succession constituting the Cuddapah Supergroup (see Table 1). Confinement of the Paleoproterozoic ultramafic-mafic sills within the clastic to shallow marine non-clastic sequences of Papaghni and Chitravathi sub basins, their configuration parallel to the basins arcuate western margin, associated Paleoproterozoic felsic volcanic, disposition of this geological domain along the eastern margin of the stabilised Dharwar craton, indicate a continental arc extensional setting for the evolution Paleoproterozoic segment of Cuddapah basin, India.
