Abstract

On the basis of lithological, palynological and megafloral data the status of Kamthi Formation has been reviewed. Hitherto known Kamthi Formation which was said to be a time-transgressive unit (Permian-Triassic) actually represents a Triassic sequence overlying Permian sediments equivalent to Raniganj Formation. The presence of Permian taxa, viz., Glossopteris, Vertebraria and Phyllotheca in red claystone, ferruginous sandstone/shale unit (=Upper Member, Kamthi Formation) represent only the continuations of Permian taxa into the Triassic.
