Abstract: The Meso-proterozoic Cuddapah basin has volcaniclast in the Vempalli and Tadipatri Formation of the Papagni sub basin. The quaternary ash beds are recorded along the number of river valleys located within the Cuddapah basin. In the Kadapa district the light several occurrences of tephra between Vamsadhara Valley in the north and the Sagileru Valley in the south. The source of the volcaniclasts of the Papagni sub-basin has been clearly identified but the source for quaternary ash beds of the Sagileru river basin is yet to be established clearly. The perusal of literature indicates the possible acidic composition of these beds. The REE pattern of these rocks is also aimed that may through light on the nature of the magma that has contributed to the formation of these beds.
