摘要: Geochemical analysis for the Mesoproterozoic clastic sedimentary rocks of basal Gulcheru Formation Cuddapah Basin in Gugudu-Dadithota-Parnapalle-Palkonda region (extending atleast 40 km) have been performed to highlight their provenance and weathering history. The low K 2 O/Al O 3 ratios representative samples points recycled nature sediments illite clay indicate an overall cold climate (low chemical degree). All diagrams a mixed source with felsic dominancy Upper continental crust (UCC) signature.
