A palynological investigation of the Lower Gondwana sediments from the Umrar River section and Umaria Coal Mine, Umaria Coalfield has been described. Four miofloral zones have been recognized. The first zone is characterized by the dominance of Callumispora+ Jayantisporites and the second zone is marked by the dominance of Parasaccites and belongs to Lower and Upper Karharbari miofloras respectively. Miofloral Zone-3 has the dominance of Scheuringipollenites, whereas Miofloral Zone-4 shows the overall dominance of striate-disaccate pollen grains representing the Lower and Upper Barakar miofloras in succession.

Bijori Formation, generally equated to the Raniganj Formation (Upper Permian) of Damodar Basin, contains a striated-disaecate dominant mioflora with abundantly represented Densipollenites and Corisaccites-Guttulapollenites and also some other miospores indicating a Permo-Triassic affinity. In the Lower Gondwana deposits of Indian Peninsula, Densipollenites-rich assemblages are characteristic of the coal-less facies towards the close of Raniganj Formation (Upper Permian). but in Satpura Basin comparable mioflora with some definite younger elements seems to exhibit Lower Triassic influence in the Upper Bijoris. By the discovery of this mioflora. the presence of a distinctive assemblage having a Lower Panchet affinity is indicated towards the top of Bijori Formation. There is, Obviously, a big scope for similar studies in the whole of Satpura Basin.

The Permian-Triassic sediments exposed along Iria Nala in the northern part of Tatapani-Ramkola Coalfield have been palynologically analysed. The palynological assemblage includes 42 genera and on the basis of quantitative dominance three assemblage zones have been distinguished in ascending order: (i) Densipollenites magnicorpus zone, (ii) Crescentipollenites fuscus zone and (iii) Falcisporites stabilis zone. The first two palynoassemblage zones are restricted to the coal, carbonaceous shale, sandstone sequence (= Raniganj Formation) which is overlain by a khaki shale bed rich in Schizoneura gondwanensis.The lithological succession above this bed contains greyish/khaki green splintery shale and sandstone (=Panchet Formation). These shales have yielded the third palynoassemblage zone marked by Falcisporites stabilis, Playfordiaspora cancellosa and Klausipollenites schaubergeri. The Permian - Triassic boundary lies above the Schizoneura gondwanensis bed between the second and third palynozones. The transition is marked by the decline in the frequency of Crescentipollenites followed with the increase of non-striate group represented by Falcisporites. The onset of Triassic sedimentation is also marked by the presence of khaki shales which closely compares with the Panchet (Lower Triassic) sediments of the type area. Thus, the transition of palynoflora from Late Permian to Early Triassic is gradual and broadly conforms with the lithological changes. There appears to be a continuous sedimentation between the Permian and Triassic periods in this part of Tatapani-Ramkola Basin.
