Core samples of Borehole MBG-23 of Gokul Block, Bandar Coalfield have been analyzed palynologically. Samples Shaly coal and shale occurring between the depth 52.3 m-43 m have been found to be rich in miospores and a statistical analysis of these samples have revealed the abundance of non-striate disaccate genera based on which Scheuringipollenires assemblage zone has been recognised which suggests Lower Barakar affinity(Ear1y Permian). This assemblage zone shows broad similarities with the Lower Barakar mioflora of other Lower Gondwana basins of India.Keywords

42 genera of palynomorphs have been reported from the qualitative and quantitative analysis of the palynoflora from both open cast mine and bore holes viz., Ballarpur open cast mine, Durgapur open cast mine and Bore hole CMWNM-57 on barrier between Kawadi/Majri open cast and Hindustan Lalpeth Colliery from the Wardha valley coalfield of Wardha basin. Two palynoassemblages have been recorded i.e., an Upper Karharbari palynoassemblage comprising dominance of radial monosaccate genus Parasaccites and subdominance of nonstriate disaccate genus Scheuringipollenites and a Lower Barakar palynoassemblage consisting of dominance of Scheuringipollenites and subdominance of striate disaccates chiefly Faunipollenites, suggesting an Early Permian age (Late Sakmarian to Early Artinskian) to the sediments. It is further authenticated by the occurrence of palynotaxa viz., Crucisaccites, Caheniasaccites, Indotriradites and Tiwariasporis. Upper Karharbari Formation has been demarcated for the first time in lithologically designated Barakar Formations in Ballarpur, Durgapur, Majri and Hindustan Lalpeth Colliery while the sample 57/2 of bore hole CMWNM from Kawadi area may belong to the Kamthi Formation on the basis of pinkish yellowish coarse grained to medium grained sandstone. An attempt has been made to correlate these palynoassemblages with other Lower Gondwana basins of Early Permian affinity.Keywords

Palynological analysis of the subsurface sediments from the bore hole 1008 (PK-6&7 blocks) from Manuguru area of Godavari graben has revealed the presence of Early Triassic palynoflora. Quantitative and qualitative palynological analysis of the productive samples have shown that the palynofossil content is predominated by cingulate-cavate spores, viz. Lundbladispora and Densoisporites and taeniate pollen like Lunatisporites in association with other taxa, such as Falcisporites, Alisporites, Klausipollenites, Chordasporites, Verrucosisporites and Osmundacidites. The above recovered palynoflora provides conclusive evidence for the presence of Early Triassic sediments equivalent to Panchet in the Manuguru area of Godavari graben. This is the first record of Early Triassic palynoflora in the Manuguru area. This corroborates the findings of Jha and Srivastava (1996) that the Lower Kamthi Formation represents the Early Triassic sequence equivalent to the Panchet Formation.Keywords
