Abstract

The palynoflora of subsurface coal-bearing sequence in cores from boreholes TC-1 and TC-2 in Kandmanglam and Marakkanam area, Tamil Nadu and Pondicherry Union Territory has been found to be rich in pteridophytic spores. The palyno-assemblage is assignable to the Coptosporo cauveriana Zone of Aptian age. The findings add to our knowledge of Gondwana coal deposits along the east coast of India.

Abstract

Palynological analysis of Bore hole RJNE-8 and RJNE-16 (drilled in the northern part of the basin) reveals presence of an assemblage which is correlatable with palynoflora of Upper Raniganj age. Appearance of elements, like Lundbladispora, Densoisporites, Lunatisporites, Goubinispora and Pretricoipipollenites indicates closing phase of Late Permian palynoflora. These results extend the presence of Upper Permian sediments up to south of village Barahat (Bara) along Godda Pirpainti Road in Rajmahal Basin.
