Abstract
This study was carried out in Hazro-Dadas (Diyarbakir) region which owns the only coal basin in the area. Chemical, petrographic analysis and organic geochemical evaluations of the Permian aged coals were taken into consideration. Coal quality investigation along with proximate (moisture, volatile matter, fixed carbon, ash) and elemental analyses (C, H, O, S, N) were performed and revealed. The huminite reflectances of organically abundant matter and coal levels were found to be between 0.458 and 1.141 % . This parameter complies with fluorescence colors, calorific value (average orijinal 3165 – 3432 Kcal/kg) and average T max coalification ranks. This is thought to be resulted from thin overburden and its possible low lithostatic pressure. Rock Eval analysis results show that Type II/III and III kerogen, with average Thydrocarbon generation. The coals are characterized with their abundance of huminite maceral group and gelinite maceral, with small amount of liptinite and inertinite macerals. Mineral matters of the Hazro-Dadas coals are clay, quartz and calcite minerals. HazroDadas coals is thought to have deposited in limnic environment swamps
