| Özet |
| In this study, petrographic and organic geochemical characteristics of the Tertiary Karlıova-Halifan coals (Bingöl) were investigated. Determination of coal quality was based on chemical (moisture, volatile matter, fixed carbon, ash) and elemental analyses (C, H, O, S, N). The values of the huminite reflectances in organic matter-rich coal levels change between 0.368 and 0.573%, which correspond to low maturity levels. These parameters are in good aggrement with their fluorescence colors, calorific value (average original-2266, dry-3177 Kcal/kg, upper calorific value) and average T max (417 oC) values. The organic material in studied coals show low grade transformation due to low lithostatic pressure. Therefore, the petrographic characteristics and quality values of Karlıova Halifan coals suggest classification as sub-bituminous coal–Lignite. Rock Eval analysis results point to an immature to early mature hydrocarbon generation for hydrocarbon derivatives formed by type II/III and III kerogen with average T max values of 417 oC. The coals mainly constitute huminites, with small amounts of inertinite and liptinite type macerals. The Karlıova Halifan coals have high contents of ash and sulphur, clay and calcites as minerals, and gelinites as individual macerals. |
