    Organic geochemical and petrographic properties of gölbaşı harmanlı (Adıyaman) coals
    (TMMOB - Jeoloji Muhendisleri Odasi, 2011) Kavak O.; Toprak S.
    This study was carried out in Gölbaşi{dotless}-Harmanli{dotless} (Adi{dotless}yaman) region where coal basin exists. Chemical, petrographical and organic geochemical analyses 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. The huminite reflectances of organically abundant matter and coal levels were found to be between 0.28% and 0.516% which refer to low maturity levels. This parameter is compatible with fluorescence colors, calorific value (average original 2736 - dry 3727 Kcal/kg) and average Tmax (422 °C). Organic matters of the investigated coals exhibit a low grade transformation, due to a low lithostatic pressure on them. In GC analyses, n-alkanes with low carbon numbers as n-C17, n-C27, n-C30 and n-C3 and CS2 as well as benzen were detected. Triterpanoid component was determined with GC-MS data and tends to imply high ground continental vegetation, but gammacera values to hypersaline depositional conditions. Gölbaşi{dotless} coals show sub-bituminous and lignite coalification ranks. Rock Eval analysis results show TYPE II/III and III kerogen, with average Tmax value is 422 °C, and corresponding to the immature and premature rank for hydrocarbon generation. The coals are characterised with their abundance of huminite maceral group with small amount of inertinite and liptinite macerals. Mineral matters of the Gölbaşi{dotless} coals are calcite, clays, and sulfur bearing minerals.

    Organic geochemical properties of adiyaman golbasi (south east of Turkey) coals
    (2011) Kavak O.; Toprak S.
    This study was carried out in Golbasi (Adi{dotless}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 (moisture, 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 Tmax (422 °C). Organic matters of the investigated coals exhibit a low grade transformation, due to a low lithostatic pressure 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 Tmax values is 422 °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. © SGEM2011 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

    Organic geochemical properties of bingol Karliova (East of Turkey) coals
    (2012) Kavak O.; Toprak S.
    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 Tmax (417°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 subbituminous and lignite coalification ranks. Rock Eval analysis results show that TYPE II/III and III kerogen, with average Tmax values is 417°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. © SGEM2012 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.

    The second paleozoic coal of Turkey, Diyarbakir-Hazro coals and their properties
    (2012) Kavak O.; Toprak S.
    This study was carried out in Hazro-Diyarbakir region (SW of Turkey), which owns a very unique coal formation. Aside from Zonguldak region (NW of Turkey), Paleozoic coal formations are very rare in Turkey. Hazro region comprises the oldest units of the region which was outcropped due to a considerably spectacular form of an anticline. Diyarbaki{dotless}r-Hazro occurrences are outcropped within the Hazro anticline. The anticline was emerged through a vast Tertiary Basin in the area. Gomaniibrik Formation, of Upper Permian age, is the main formation of the region. The formation which contains of shale, sandstone succession and is of lacustrine type formation comprises of two important coal levels. Chemical and petrographic analyses of the coals were taken into consideration. Coal quality investigation along with proximate (moisture, volatile matter, fixed carbon, ash) analyses were performed and revealed. The coals herein, as a result of conducted detail prospects and drills, comprises of 0.2 - 1.9 meter thickness, 1.2% moisture, 30% ash, 5100 Kcal/kg calorific value and 2.3 million total reserve. The vitrinite (huminite) is the most common maceral and its reflectances (Rmax) were found to be between 0.46 and 1.14% which refer to medium maturity levels. The coals seem to show sub-bituminous to bituminous coal ranks. The mineral matters of the Hazro coals are mostly clays, calcite and pyrite. © SGEM2012 All Rights Reserved by the International Multidisciplinary Scientific GeoConference SGEM.
