In the Korba sub-basin an effort has been made to study the coal facies with the help of maceral content, microlithotypes, chemical constituents of coal and by depositional milieu. Macerals like vitrinite when associated with sporinite strongly characterised freshwater conditions. i.e.. limnic and telmatic. Microlithotypes of this sub-basin mostly reflect conditions of a high groundwater level in a swamp forest. Microlayering observed in clarites suggest a certain phase of stagnant water conditions in a subsiding sub-basin. Durite indicates sub-aquatic facies. Carbominerite is more useful in studying lateral facies and the decrease of carbominerite content towards the eastern part of the sub-basin points to the existence of eutropic swamp conditions. The low concentration of boron. low sulphur content and the presence of germanium in all blocks of the sub-basin reflects limnic and telmatic coal facies in freshwater swamps. The depositional milieu favoured the existence of limnic and adjacent telmatic conditions.
