Permian palynological assemblages in the Godavari Graben

Abstract

Palynological investigations carried out in the Godavari Graben during the last three decades have led to suggest the existence of nine palynozones from the Talchir to Kamthi formations. The Talchir Formation palynological assemblage, though dominated by the presence of radial monosaccate pollen grains, exhibits evidences of fluvio-glacial and lacustrine environment of deposition alongwith periodical influence of marine incursions. The presence of Karharbari and Barren Measures (Kulti) as distinct formations has been substantiated with palynological data. The occurrence of Corisaccites-Guttulapollenites palynozone and Densipollenites palynozone in the Middle Member of the Kamthi Formation represents the uppermost Permian palynoflora in Godavari Graben.
