Abstract	Coal samples from Poniati, Dishergarh, Samla, Narainkuri and Nega seams (top and bottom) from Raniganj Coalfield were examined microscopically to know the physical composition and nature of the coal seams. The study reveals that then coals are banded component types derived from heterogenous phyto-organic materia!. Lignogene (Vitrinite) constituents derived from lignified cell walls are conspicuous microcomponents of the coals. 'Liptogene (Liptinite) constituents derived from pollen and spore coat, plant cuticles andfusinised resins form secondary proportions in the coal composition. The macerated coal consists of tracheids, cuticles, spores and pollen. About 20 genera were identifiedin conformity with the latest trends in spore morphography. The most frequently encounteredspore genera in descending order are Striatopieeites, Sulealisporites, Striatopodoearpites, Horriditriletes, Cyclogranisporites, Thymospora, Leiotriletes and other minor forms Major portion of organic constituents were probably derived from rich gymnospermous flora and the later coal-forming swamps were coalified mostly by Vitrinization process. It is apparent that during the formation of the peat the cell wall substances reacting to biochemical dissolution and decay were humified arresting the disintegration and the plant material became compacted initiating the vitrinization.
