| Abstract: | A detailed study of maceral composition and vitrinite reflectance of the coal deposits from Marki-Jhari-Jamni area, situated
in the northwestern extremity of Wardha valley coalfield, Yeotmal district, Maharashtra has been carried out with special
reference to their depositional set up. These coals have two distinct types of maceral organization, one having significantly
high distribution of the vitrinite group of macerals (35–41%) and the other containing the dominance of inertinite (26–49%).
Liptinite maceral group is recorded between 14 and 24%, barring a few coal bands having liptinite maceral group as high as
33–37%. The vitrinite reflectivity ranges from 0.38–0.43%. Thus, they have attained sub-bituminous C rank. Mineral matter
in these coals varies between 15 and 22%. The present study suggests that the basin primarily experienced cold climate having
intermittent brackish water influx with alternating dry oxidizing spells. |
