Özet
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, and S, N) were performed and revealed. The huminite reflectance 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 original 3165 - 3432 Kcal/kg) and average T-max (418 degrees C). Hasbro coals show low grade maturity and own sub-bituminous, bituminous 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 T-max value is 418 degrees C and corresponding to the immature and early-mature rank for hydrocarbon 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. Hazro-Dadas coals are thought to have deposited in limnic environment swamps.
