Abstract

The present work details the results of the palynological studies carried out in the Umrer Coalfield of Wardha Basin of Maharashtra State, Central India. The coalfield covers an area of 4 sq. km and is characterized by three coal seams designated as bottom, middle and top seams with partings. Statistical analysis of the palynomorphs from these sediments have revealed the dominance of radial monosaccate pollen grains of the genus Parasaccites and subdominance of non-striate bisaccate genus Scheuringipollenites in association with other typical early Permian taxa viz. Crucisaccites, Callumispora, Caheniasaccites, Brevitriletes, Tiwariasporis and Primuspollenites. This association characterizes the palynoflora of the upper Karharbari Formation of India on the basis of which the Umrer Coalfield has been assigned an early Permian late Sakmarian to early Artinskian age. It is further authenticated by the presence of the species Crucisaccites monoletus significant of the Karharbari Formation. Age deductions have also been made by correlations with similar assemblages from different basins in India and early Permian palynoflora from other Gondwanan continents some of which have been associated with radiometrically dated sediments.
