The arcuate north, south and western boundary of the Cuddapah basin marks the profound uncomformity called Eparchaean Unconformity in early literature on basement granites enclosing the Eastern greenstone belts in Kadiri, Veligallu and Tsundupalle in the south, and Raichur, Gadwal and Peddavuru in the north.
The Papaghni and Kurnool sub-basins are geographically interlinked, but were sites of deposition at different times, the Papaghni sub-basin containing lower Cuddapah sediments, and the Kurnool sub-basin containing the younger Kurnool sediments that overlie the Cuddapah sequence with a major unconformity.
The author recommends further detailed structural bqsin, especially in the eastern half of the basin, for solving the unsolved problems in the Cuddapah stratigraphy and structure. The early sediments of the basin are interspersed with basic volcanics and sills.
Cuddapah Basin, South India
The relation of the structural elements to the localization of mineral deposits in the Cuddapah Basin is discussed and the necessity for their precise interpretation for exploring the depth extension of the ore mineralization is stressed.
Cuddapah basin is characterized by quartzite-carbonate-shale cycles having an aggregate thickness that is estimated to vary between 6 and 12 km. The arcuate eastern margin is marked by a prominent boundary thrust, which is parallel to the Nellore schist belt, Eastern Ghats mobile belt and the East Coast.
Future Challenges in Earth The basin extends for a length cuddapau about km along the arcuate eastern margin with a mean width of km, and is the second largest Purana basin of Penninsular India, after the great Vindhayan basin. Naqvi Gold Medal K. Vaidyanadhan Award Endowment Lecture C.

The basin is well known for its mineral potential in the form of limestones and dolomites, bedded and basn barites, chrysotile asbestos and steatite, besides occurrences of base metals, diamond, phosphorite, uranium and abundant building and ornamental stones.

A giant basic dyke swarm underlies the basin in the west from Chittoor in the south to Mahbubnagar in the north. This is further bsin by a major domal upwarp baisn the middle of the basin marked by monocjinal flexures of the Kurnool strata in Gani Kalawa area; culminations and depressions at Jammalamadugu, Giddaluru and Srisailam plateau; Eshwarakupam dome of the lower Cuddapahs in the northern part of the Nallamalai hills; and granite domes of Vinukonda area in the north-east extremity.
The Cuddapah Basin in Andhra Pradesh is a remarkable tectonic and orogenic belt of the unfossiliferous Precambrian rocks of Peninsular India. The western half of the basin is undeformed and consists of four sub-basins, the Papaghni, Cudda;ah, Srisailam and Palnad.

Cudadpah eastern half of the Cuddapah basin is occupied by the Nalamallai fold belt consisting of upper Cuddapah sediments. A north-plunging low-amplitude asymmetrical synclinorium having a gently dipping western limb and intensely folded, overfolded and thrusted eastern limb is the major structural element.
Srisailam sub-basin contains upper Cuddapah sediments and Palnad sub-basin exposes only the younger Kurnool sequence. Felsic volcanics and tuffs are intercalated with sediments at many horizons.

Karanth Endowment Lecture T. Mahadevan Endowment Lecture R. Nallamalai fold belt is demarcated from the undeformed western sub-basins by the prominent fault lineament called the Rudravaram Line along which cleavage begins to develop in the Cuddapah sediments, which become intensely deformed cudadpah the boundary thrust in the east.
