ORGANIC GEOCHEMICAL PROPERTIES OF ADIYAMAN GOLBASI (SOUTH EAST OF TURKEY) COALS
Abstract
This study was carried out in Golbasi (Ad Д±yaman) region (SE of TURKEY), which owns rare coal formations 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 (m oisture, volatile matter, fixed carbon, ash) and elemental analyses (C, H, O, S, N) were performed and revealed. The huminite reflectance of organically abundant matter and coal levels were found to be between 0.30 and 0.52% which refer to lower maturity levels. This parameter is compatible with fluorescence colors, calorific value (average original 2736 - dry 3727 Kcal/kg) and average T max (422 o C). Organic matters of the investigated coals exhibit a low grade transformation, due to a low lithostatic pre ssure on them. Golbasi coals show low 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 422 o C and corresponding to the immature and premature rank for hydrocarbon generation. The coals are characterized 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 and were supposed to form as a hypautochtonous way. Mineral matters of the Golbasi coals are clay, calcite and sulfur minerals.
