Özet:

This study was conducted with the aim of determining the organic geochemical properties of Early-Middle-Miyosen-Old Coal and the potential of hydrocarbon species, as well as the paleo-mediate properties.  In this framework, detailed organic geochemical and organic petrographic analyses were carried out in coal samples collected from the three coal fields located in the north of the Zorum (Incesu, Evlik and Alpagut-Dodurga). Organic geochemical assessments; TOC-Rock-Eval pyrolysis analysis, gas chromatography, gas chromatography-mass spectrometer analysis, the amount of organic substance that forms coal, the type and the elements that are active in the process of coal formation have been tried to determine. Rock-Eval analysis results indicate that the type II/III mixture and type III kerogen are dominant in coal and organic substances-rich samples. The organic compounds of coal are more composed of huminite group maserals, and in less proportions of inertinite and liptinite groups. Coal has a high composition of ashes and sulfur, and there are some differences in the fields studied. According to the Petrographic and Biomarker data, these coins can be said to have a deforestation environment, or a lake deforestation. Furthermore, while coal has the potential to produce gas rather than oil in terms of the quantity and type of organic substance, the possibility of this type of formation is very low because of its low maturity.
