The lower part of the Proterozoic Cuddapah Basin exposes three quartzite sequences, namely, Gulcheru, Pulivendla, and Gandikota formations. Gulcheru Quartzites show angular to subangular texture, whereas Pulivendla and Gandikota quartzites contain rounded to subrounded detrital grains. Mineralogically, all quartzites are predominantly composed of quartz with subordinate amount of feldspar, mica, and heavy minerals. Clay and silt are present as a matrix while silica and carbonate act as a cementing material. Based on detrital modes and major element geochemistry, these sediments are classified as arkose to subarkose. The petrological and geochemical attributes of the basal formations of the Cuddapah quartzite indicate cyclic weathering under variable humid subtropical climate. The CIA values of these quartzites suggest moderate to intense chemical weathering for the Gulcheru and Gandikota quartzites and low to moderate chemical weathering for Pulivendla Quartzites. The major element ratios (SiO2/Al2O, K2O/Na2O), trace element ratios, chondrite‐normalised REE patterns and UCC normalised multi element diagrams suggest that these quartzites were predominantly derived from the felsic sources, with subordinate contribution from mafic sources. Provenance studies and mixing models, in conjunction with palaeocurrent data suggest that these quartzites of the Lower Cuddapah Supergroup received sediments from various sources including Eastern Dharwar Craton as well as from more juvenile crust.
