Stratigraphical notes on the standard sequence of the Upper Gondwanas of India

Abstract

Recent additions to the knowledge of the geological history and the floral characters of the various Gondwana members in India necessitate to revise the so far accepted standard sequence of the Upper Gondwana formations. A new scheme based on the geological history and the palaeobotanical characters of the beds is here proposed. The sequence is represented by Mahadeva and ]abalpur series (in the revised sense). The former consists of two stages - Pachmarhi and Denwa, while the latter consists of four floristic zones corresponding to: Parsora, Rajmahal, Nipania and Bhuj.
