The basin is well known for its mineral potential in the form of limestones and dolomites, bedded and vein 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. Progress Report of G. Sawkar endowment for Teachers training V. A north-plunging low-amplitude asymmetrical synclinorium having a gently dipping western baskn and intensely folded, overfolded and thrusted eastern limb is the major structural element. How to cite item.
Cuddapah basin is characterized by quartzite-carbonate-shale cycles having an aggregate thickness that is estimated to vary between 6 and 12 km. 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 arcuate north, south and western boundary of the Cuddapah basin marks the profound cudeapah called Eparchaean Unconformity in early literature on basement granites enclosing the Eastern greenstone belts in Kadiri, Veligallu and Bzsin in the south, and Raichur, Gadwal and Peddavuru in the north. Nallamalai fold belt is demarcated from cuddapab undeformed western sub-basins by basjn prominent fault lineament called the Rudravaram Line along which cleavage begins to develop in the Cuddapah sediments, which become intensely deformed towards the boundary thrust in the east.
Felsic volcanics and tuffs are intercalated with sediments at many horizons. Srisailam sub-basin contains upper Cuddapah sediments and Palnad sub-basin exposes only the younger Kurnool sequence. Article Tools Print this article.
