B1 Dept. of Geology, Yogi Vemana University, Kadapa-516005, Andhra Pradesh, India Abstract: The crescent shaped Cuddapah basin located Annamalai Surface - at an altitude of over 8000’ (2424 mainly in the southern part of Andhra Pradesh and a m), ii. Ootacamund Surface – at 6500’-7500’ (1969- little in the Telangana State is one of the Purana 2272 m) on the west and at 3500’ (1060m) on the east basins. Extensive work was carried out on the as noticed in Tirumala hills, iii. Karnataka Surface - stratigraphy of the basin, but there is very little 2700’-3000’ (Vaidynathan, 1964). 2700-3300 reference (Vaidynathan,1964) on the geomorphology of (Subramanian, 1973) 2400-3000 (Radhakrishna, 1976), the basin. Hence, an attempt is made to present the iv. Hyderabad Surface – at 1600’ – 2000’v. Coastal geomorphology of the unique basin. The Major Surface – well developed east of the basin.vi. Fossil Geomorphic units correspond to geological units. The surface: The unconformity between the sediments of the important Physiographic units of the Cuddapah basin Cuddapah basin and the granitic basement is similar to are Palakonda hill range, Seshachalam hill range, ‘Fossil Surface’. Gandikota hill range, Velikonda hill range, Nagari hills, Pullampet valley and Kundair valley. In the Cuddapah Basin there are two major river systems Key words: Topography, Land forms, Denudational, namely, the Penna river system and the Krishna river Pediment zone, Fluvial.
