Abstract

Manish Kumar Mishra and D.P. Pandey

Experimental results of the study of the correlation of mineralogy with their geological formation are reported. These results suggest that high proportions of ash as up to 45% present in Gondwana coals of Jharia are confirmed by x-ray differaction analysis and I.R. spectrocopy. The high mineral matter of such coals was in all probability incorporated during the transportation or 'drifting' of the vegetable matter. These coals are also typified by the simultaneous presence of very low percentage of vitreous layers. These results suggest that the mineralogy of the coals of Jharia can be satisfactorily accounted for in terms of the drift origin of the Gondwana formation.
