Palynological Delimitation of the Coal Bearing Lower Gondwana Sediments in the Southern Part of Tatapani-Ramkola Coalfield, Chattisgarh, India

Coal and carbonaceous shale samples from bore-hole TRSS-1, located in the southern part of Tatapani Ramkola Coalfield have been palynologically analysed. Surface sediments exposed in the vicinity of the bore-hole, along Suknaiya nala, were also examined to ascertain their stratigraphic position vis-a-vis the bor' "oIe sediments. On the basis of quantitative dominance, three assemblage zones have been distinguished. which in ascending order are: (i) Parasaccites-Callumispora palynoassemblage zone, (ii) Scheuringipollenites maxim us palynoassemblage zone and (iii) Faunipollenites-Scheuringipollenites palynoassemblage zone. The first two assemblage zones have been demarcated in bore-hole TRSS-1 and represent Upper Karharbari and Lower Barakar palynozones respectively. The third assemblage zone has been recorded in Suknaiya nala and represents Upper Barakar palynozone.
