Abstract

The present paper includes a sporological study of 53 bore hole coal samples from Bhaskarpara, Kutkona and Batura blocks of Sohagpur Coalfield, M.P., India. The distribution of various palyno-taxa among the samples has suggested the occurrence of eight coal seams distinguished by eight spore assemblages. Miospore Assemblage G is characterized by the dominance of Brevitriletes and   Sulcatisporites. The Assemblage F shows a dominance of Brevitriletes closely associated with Microbaculispora and Indotriradites. The last genus becomes dominant in Assemblage E1 with the former two as subdominants. In Assemblage E, the subdominants are Hennellysporites and Illinites. Brevitriletes again ranks highest in Assemblage D and is associated with subdominant Sulcatisporites. In Assemblage C, Brevitriletes continues to be dominant but the association is marked by the subdominance of Horriditriletes and Sulcatisporites while in Assemblage B Horriditriletes becomes the most dominant genus and remains associated with Brevitriletes and Sulcatisporites. Assemblage A is characterized by the dominance of Sulcatisporites in association with Striatopodocarpites and Striatites.

The sporological succession is marked by three miofloral changes segregating four groups of assemblages. Chronostratigraphically, Assemblage G belongs to Lower Karharbari Stage, Assemblages F-E represent Lower Barakar Stage, Assemblages D-B represent Middle Barakar Stage and Assemblage A represents the Upper Barakar Stage.
