Abstract

Palynological investigation of bore-hole GAM 7 from Mailaram area (Paloncha neck) in Godavari Graben has revealed five assemblages. Assemblages I to IV represents late Permian being dominant in striate disaccate pollen. Assemblage V denotes an Early Triassic age in view of the preponderance of Lunatisporites pellucidus and Verrucosisporites. The changeover from striate-disaccate to taeniate phase is quick and sharp indicating a palynological break. The transition from Permian to Triassic in this part of Godavari graben occurs in a paraconformable. The Permian- Triassic boundary passes within a gap of 12 m and a definite presence of Panchet palynoflora is established.
