Swamy Sharan & K.David Department of Geology, KakatiyaUniversity, Warangal-506009, T.S. ABSTRACT Pranhita-Godavari (P-G) Basin occurs in two parallel NW-SE trending sub-basins the western and the eastern), situated at the junction of Dharwar and Bastarcratons, anddeveloped after amalgamation of the craton in palaeoproterozoic. Three sub-basins are identified in this P-G basin. They are namely eastern Albaka, central Pakhal, and western Chandarpur. The aggregate thickness of the sediments of the P-G basin is estimated at about 6000mt. The Pakhal belt extends from Khammam in the south to Adilabad in thenorth. The Albaka belt extends from Bhadrachalam in the south to Chandarpur in thenorth. The P-G Basin sediments deposited in a time span of 200.Ma from lateCarboniferous/early Permian to Cretaceous.Generalisedlitho-stratigraphic succession ofthe Gondwana sediments includes Talchir, Barakar, Barren measures, Kampthi (lowerGondwana group) Maleri, Kota, Gangapur and Chikial formations (upper Gondwanagroup). Two Proterozoic succession of the P-G super group are divided into four majorgroups, namely Mallampalli, Mulugu, Penganga and Sullavai separated by three regional unconformities. The sediments of the P-G basin strike NW-SE with moderate dips towards NE. A 3000mt. thick Gondwana lithic fill consisting of multifacies associationsis preserved in this NW-SE oriented intra-cratonic basin set across the EasternGhatComplex (EGC). The depositional environment varied from galcio-lacustrine to highly sinuous fluvial. The P-G basin is among the Indian Sedimentary basins that have been identified as having hydrocarbon potential. Two blocks have been awarded in the basin PG-ONN-2-1/1 and GN-ON-90/3, while work in the block GN-ON-90/3 has been heldup due to the Naxalite problem for the past 13 years. The block, PG-ONN-2001/1 was awarded to ONGC under the NELP-III in 2003 and is the only block awarded in the P-Gbasin in the NELP era. The other block, GN-ON-90/3, was awarded in the
