“…In general, the intensity of chemical weathering increases when there is a decrease in tectonic activity and/or warm and humid conditions prevail in the source region (Jacobson, Blum, Chamberlain, Craw, & Koons, ). Aeolian sedimentary structures have been reported from the basal most part of the Gulcheru Formation (Basu, Suryanarayana Sastry, Achar, Umamaheswar, & Parihar, ). However, there are frequent preservation of fluvial sedimentary structures in the upper part of the horizons, which suggests that the sedimentation was initially taken place in the arid climate which subsequently changed to subtropic humid climate (Basu et al, ).…”

The A–CN–K plot is also a valuable tool to estimate fresh rock compositions and examining their weathering trends since unweathered primary igneous rocks have CIA values close to 50 (Fedo et al, ).…”

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.

“…Although several aeolian erg successions of Proterozoic age have been described previously (see Rodríguez-López, 2014 and references therein), and some have been the subject of facies analysis for the purpose of reconstruction of palaeoenvironment (Deynoux et al, 1989;Chakraborty, 1991;Simpson and Eriksson, 1993;Biswas, 2005;Basu et al, 2014), the aeolian succession of the Mangabeira…”

“…3 1991; Simpson and Eriksson, 1993;Basu et al, 2014;Heness et al, 2014). Studies of Proterozoic successions are notably important for determining aeolian-system dynamics that prevailed prior to the evolution of land plants; results of such studies find direct application to gaining an improved understanding of sedimentary processes that prevailed on other planets, for example aeolian processes on Mars, where different ancient and recent deposits (Sullivan et al, 2005;Hayes et al, 2011) of aeolian dunes have been identified.…”

The Gulcheru Quartzite (30-200 m thick) overlies Archaean basement rocks, and comprises an impersistent conglomerate at the base of more widespread quartzites, with shale and ferruginous interbeds. The overlying Vempalle Formation (1500 m) comprises mainly stromatolitic carbonates, lesser cherts and mudrocks. Together, these two units make up the Palaeoproterozoic Papaghni Group, which displays an arcuate outcrop belt in the SW Cuddapah Basin, bearing no obvious relationship to the tectonic grain in the basement lithologies. Facies defined in the Gulcheru Quartzite are ascribed to initial alluvial fans, which transitioned into a shallow-marine coastline and shelf, as transgression occurred under overall thermal subsidence, possibly related to post-plume thermal relaxation. The shallow siliciclastic Gulcheru shelf is inferred to have evolved to a stromatolitic ramp that accommodated deposition of the Vempalle chemical sediments. The abrupt vertical transition from clastic to carbonate deposits is ascribed to rapid sea-level rise. Late-stage shoreline progradation during uppermost Vempalle times and concomitant clastic inflows terminated the carbonate factory.
