Miospore assemblage in some coals of Barakar stage (Lower Gondwana) of India

Abstract

Sporae dispersae have been referred to 53 miospore genera with 131 species out of which 59 species are new. For each species a large number of specimens have been studied and the probable range of variation in the qualitative as well as quantitative characters within a species has been determined. For specific delimitation the association of morphographic characters has been given primary importance. New species have been diagnosed, described and compared in detail. The qualitative and quantitative compositions of the assemblages from Korba Coalfield and W. Bokaro Coalfield have been compared. It has been concluded that the mioflora of Korba Coalfield is divisible into an older and a younger assemblage. The younger assemblage shows some closeness with the miofiora of W. Bokaro Coalfield.
