Determination of degree of coa&ification by reflection "measurement to the Değirmentaşı (Artvin) antracite deposit.

ABSTRACT: Lias aged antracite deposit at East Pontides was tbought to` contain, graphite upon prospecting`. During the exploration work started in this direction, coal petrography studies- were carried. out besides the ^eologic and tectonic evoluation of the area. At the result of the research study, coalilicatiom. degree of the Lias aged depissit was determined by reflection measurements. High caü£ica£ioii degree^ bo`ng affected by granite ascendance corresponds to Laramian phase. Iıı this paper only results obtained from the pétrographie investigation of coal are given
