Abstract

In a previous paper, the author has indicated the nature and importance of palynopetrographic approach of coals. To serve as an example of the results which may be obtained by the application of this method of study, a brief review of the work done by him in regard to two coal seams is given here.

Abstract

As the very title of the paper indicates, the two aspects of Coal viz., palynology and petrography are necessary for a complete study. It is known that there exists an intimate genetic relationship between the microfossils and petrographic components of coal. No serious attempt however has so far been made for an integrated palynopetrographic study which can resolve the complex nature of coal. In this paper some methods for the study of microfossil and maceral components of coal, their association and utility from the point of view of the present approach are briefly described; and these help us in understanding the complex nature of coal.

Abstract

Microscopic examination of polished pellets of Churcha coals reveals the nature of microfragmental constituents comprising mostly Durains. Petrological analysis has been made so as to assess the nature and distribution of different microconstituents. The miospore assemblage in this seam is a diversified one, consisting of 36 genera of triletes, monoletes, monosaccates, disaccates and others. The percentage frequencies of various genera have been determined. Petro-palynological constituents of this coal have been compared with those of other comparable beds in the Lower Gondwana of India.
