Early Permian micro and megaspores from the Nand-Besur Block, Bandar Coalfield, Wardha Basin, Maharashtra, India

Abstract

The sub–surface samples of bore core NP–75 drilled near Nand Village, a part of Nand–Besur Block of Bandar Coalfield, Wardha Basin, Maharashtra have yielded palynomorphs which include spores/pollen grains and megaspores. The pollen assemblage shows the dominance of the genus Scheuringipollenites and sub–dominance of Faunipollenites (=Protohaploxypinus) along with Caheniasaccites, Plicatipollenites, Potonieisporites, Barakarites, Arcuatipollenites, Striatopodocarpites, etc. Megaspores are represented by three genera and nine species comprising Bokarosporites rotundus, Bokarosporites sp., Jhariatriletes filiformis, Singhisporites baculatus, S. indica, S. nautiyalii, S. radialis, S. surangei and Singhisporites sp. The palynomorph assemblage indicates an early Permian age equivalent to the lower Barakar Formation.
