Sporological correlation of coal seams in Bisrampur coalfield, M.P., India

Abstract

Sporological study of 21 bore-core coal samples from Bhatgaon, Khargaon and Songara blocks of Bisrampur coalfield, M.P., has been done. The qualitative as well as quantitative distribution of various palyno-taxa among the samples, has suggested the occurrence of four distinct miospore assemblages. Assemblage-A is marked by the higher representation of Microbaculispora associated with Dentatispora. Assemblage-B is characterized by the dominance of Indotriradites, while Assemblage-C has the dominance of Brevitriletes in association with Sulcatisporites and Assemblage-D is dominated by an association of Brevitriletes, and Horriditriletes. These four palynological assemblages suggest the occurrence of four coal seams among the samples investigated.
