Abstract
In the eastern Dharwar craton, the crescent- shaped Cuddapah Basin forms a large intracratonic basin, comprising Meso–Neoproterozoic sedimentary sequence with volcanic rock components. The sedimentary environment of the Cuddapah Basin, in general, is comparable with peri-tidal complex with shallow marine carbonate shelf and beach environment. Systematic geological studies of the Cuddapah Basin are well documented1,2. The litho-units of the basin are mainly divided into older Cuddapah Supergroup and a younger Kurnool Group. The former is present throughout the basin, while the younger group is seen in its western and northeastern parts. The sediments of the basin overlie the Late Archaean–Lower Proterozoic granitoids intruded by basic and ultrapotassic dykes.
