ORGANIC GEOCHEMICAL PROPERTIES OF BINGOL KARLIOVA (East of TURKEY) COALS

This study was carried out in Halifan (Bingol) region (East of TURKEY), which owns a unique coal formation in the region. Chemical, petrographic analysis and organic geochemical evaluations of the Tertiary 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 0.368 and 0.573% which refer to lower maturity levels. This parameter is compatible with fluorescence colors, calorific (average 2736 (original) - 3727 (dry) Kcal/kg) and average T-max (417 degrees C) values. Organic matters of the investigated coals exhibit predominantly medium grade transformation, due to the extensively effective main faults in the region. Halifan coals show low-medium grade maturity and own sub-bituminous and lignite coalification ranks. Rock Eval analysis results show that TYPE II/III and III kerogen, with average T-max values is 417 degrees C and corresponding to the immature and premature rank for hydrocarbon generation. The coals are characterised with their abundance of huminite maceral group and gelinite maceral, with small amount of inertinite and liptinite macerals. The coals were deposited in a lake environment. Mineral matters of the Bingol Karliova coals are clays, quartz and feldspar minerals..
