4 Glossopteris leaves alongwith the occurrence of Schizoneura gondwanensis, Trizyzia speeiosGJ Stellatheea robusta and other Lower Gondwana ferns. The miospore assemblages show a dominance of striate·disaccate forms alongwith Scheuringi~ pollellites, Demipolllnites and other trilete forms. These assemblages suggest an Upper Raniganj age for this bed. 2.4. Fossil wood from Raniganj Coalfield, West Bengal One fossil wood has been identified as a new genus J>alaeospirox'ylon. 2.5. Sporae dispersae and palynostratigraphy 2.5.1. Palynostratigraphy of Lower GondWalZG Formation, Hular Coalfield The palynostratigraphy of the Hutar Coalfield has been completed and the results of this study have been incorporated in a Ph.D. Thesis. The highlights of the work are: (i) Demarcation of Karharbari Formation in the Hutar Coalfield on the basis of lithological and palynostratigraphical evidences; (ii) Indication of the possibility of the Barren Measure Formation in this coalfield on the palynological evidences; (iii) Recognition of 6 biozones in the Lower Gondwana Formation ofHutar Coalfield, viz., Zone- VI Barren Zone Zone- V Densipolleniles-Scheuringipollenites Faunipolleniles Assemblage zone (Upper Barakar). Zone-IV Scheuringipol/rniles-Slriasulciles Assemblage zone (Barakar).
Zone-II I P arasaccifes-Scheuringipoilinites zone (Upper Karharbari), Assemblage 5 Zone- II Parasaccites-Callumispora Assemblage zone (Lower Karharbari). Zone- I Parasaccites-Plieotipollenites Assemblage zone (Talchir». The extension of these biozones in the Lower Gondwana beds of other coalfields has also been traced. 2.5.2. Morphotaxonomic study of Trilete genera The monograph on the miospore group Varitrilctes has been completed and the morpho taxonomic study of the Corisaccites-Gultulapollenites-complex is being continued. 2.5.3. Permo-Triassic palynology Palyno-dating of the samples from bore-cores from East Raniganj coalfield proves the extension of Permo-Triassic deposition of the Raniganj Coalfield beyond its present limits, towards the eastern side. The subsurface coal deposits in the eastern part of the \-Vest Bengal basin have thus been indicated. The Permian-Triassic sediments of Tethyan Himalaya, Malia Johar area have indicated a palynological affinity with the Gondwana deposits of the Indian peninula, rather than wirh the European of Angara region. It has been concluded that the original provenance of the Tethyan Permo·Triassic deposits was in the Indian Plate. 2.5.4. Detailed morphographic studies of sporae dispersae from Giridih Coalfield, Bihar and from Siang District, Arunachal Pradesh art" being continued, while palynostratigraphic studies of the Lower Permian sediments
