Training Programme on “PALYNOLOGY IN FOSSIL FUEL EXPLORATION” [ September 10-17, 2012 ] DR. RATAN KAR Scientist - C Birbal Sahni Institute of Palaeobotany 53, University Road Lucknow 226 007 E-mail: ucp6@rediffmail.com Obtained Post graduate degree in Geology from Lucknow University. Qualified the CSIR-UGC NET JRF Exam. Awarded Ph.D. in Geology on his work entitled “Palynostratigraphy of Gondwana sediments from Tatapani-Ramkola Coalfield, Surguja District, Madhya Pradesh, India”. He was also warded the ‘Dr. Pratul Chandra Bhandari Gold Medal’ for this. Specialisation in Palynology: Has worked on a wide range of problems of varying ages and areas which involve the use of palynofossils for their resolution, such as Gondwana sediments (Permiam-Triassic), Deccan Intertrappean beds (Upper Cretaceous-Early Palaeocene) and Quaternary fluvio-glacial & lacustrine deposits of the Higher Himalayas and the Arctic Region. He has awarded a number of sponsored projects, viz.: � DST sponsored Young Scientist Fast-Track Project on the Deccen intertrappeans – “Palynological, Biopetrological and Dispersed Organic Matter (DOM) study of Deccan Intertrappean sediments with reference to Cretaceous-Tertiary (K-T) transition”. � DST sponsored pilot project on Glaciology – “Palynology and sediment-geochemistry of Hamtah (Lahaul-Spiti) and Chaurabari (Kedarnath) glacier deposits: an investigation of high-altitude climate variability during Holocene”. � DST sponsored project under Climate Change Programme – “Analysis of climatic changes from glacial sites in India based on multi proxy data”. � CSIR Pool Officer Project on Chaurabari Glacier, Kedarnath – “Palynological studies around Chaurabari Glacier (Kedarnath) with reference to climatic changes and glacial fluctuations during Holocene”. Under the Arctic Project entitled Multi-proxy geological studies in Svalbard area and surrounding Ocean: Implications to Quaternary Palaeoclimate and Pre-Quaternary Biostratigraph, he Visited Arctic three times and was Team Leader in 2011 (Summer Batch-III). He is also a Member, Terrestrial Working Group, International Arctic Science Committee. He has published 33 research papers in national and international Journals (19 in Impact Factor Journals).

Training Programme on “PALYNOLOGY IN FOSSIL FUEL EXPLORATION” [ September 10-17, 2012 ] APPLICATION OF PALYNOLOGY IN COAL EXPLORATION: CASE STUDY FROM AN INDIAN GONDWANA COALFIELD RATAN KAR Birbal Sahni Institute of Palaeobotany, 53, University Road, Lucknow 226 007 E-mail: ratankar@yahoo.com Gondwana Basins of India occur along several well defined rectilinear belts marking zones of structural weaknesses. These basins are intracratonic in nature and characterised by the presence of faults on both sides, known as the boundary faults. These linear depressions became ideal sites for the deposition of sediments. A characteristic feature of sedimentation in these depressions was the concomitant sinking of the basin floor, which resulted in the deposition of thick piles of sedimentary sequences. From the economic point of view, the Gondwana Basins are extremely significant as 99% of India’s coal reserves are present within these basins. The initiation of sedimentation in Peninsular Gondwana Basins of India breaks a long gap of nondeposition in this region, since Cambrian to Late Carboniferous/Early Permian. The sedimentation was initiated by the deposition of glacigene sediments of Talchir Formation on an uneven Precambrian basement. After the recession of glaciers, a prolonged sequence of continental fluvio-lacustrine sediments was deposited. The first phase of fluvial sedimentation is represented by the Karharbari Formation, comprising poorly sorted coarse-grained sediments, the tectonic set-up being too unstable for the accumulation of coal seams. Thereafter, conditions became stable and thick piles of coarse to mediumgrained sandstone, siltstone, shale and coal-seams were deposited comprising the Barakar Formation (early Permian). The succeeding Barren Measures Formation are composed of coarse to medium-grained cross-bedded sandstone and iron-stone shales and are devoid of coals. Favourable conditions for coal formation reappeared again during the deposition of sediments of Raniganj Formation (late Permian). The post Raniganj sedimentation (Triassic) is characterised by the deposition of varied type of sediments in different Gondwana Basins, which are completely devoid of coal and comprise mainly of red shales and pebbly coarse to medium-grained sandstones. The commercially viable coal seams occur mostly within the Barakar Formation and the estimation of reserves is done by extensive mapping, followed by drilling operations. In this context, proper identification of the coal bearing horizons is extremely important for optimizing drilling operations and for the correct estimation of reserves. As lithological demarcation of the different formations is often difficult and deceptive, palynology has proved to be an effective tool for the resolution of coal bearing strata. Palynological assemblages have been of immense use in determining the age, lateral extension and correlation of the surface and sub-surface coal bearing horizons.
