Palynology of Kamthi Formation from Ramagundam-Mantheni Area, Godavari Graben, Andhra Pradesh, India

Abstract

Palynological study of the Kamthi Formation from the Ramagundam-Mantheni area of Godavari Graben reveals that the palynoflora of Kamthi Formation is uniformly dominated by striate-disaccate (about 50%) and the subdominant groups differ. Thus Lower Member of the Kamthi Formation is characterised by the subdominance of nonstriate-disaccates while Middle Member is characterised by the subdominance of Striasulcites in the older part and Densipollenites in the younger part. The palynoflora is by and large comparable with the Raniganj palynoflora of Damodar Valley except a few differences. The palynoflora in the upper part of the cored Middle Member of Kamthi Formation exhibits close proximity towards Permian-Triassic (Panchet) transition. Obviously, only the Lower and partly Middle members of the Kamthi Formation are homotaxial with Raniganj Formation of Damodar Basin.
