The classification of organic fades is made with respect to t lie chemical properties of kerogene, maseral types, and microscopic analyses. Seven types of organic fades are defined considering the composition, formation and diagenetic condition of organic matter.The formation with the characteristics of the source rock in tlie study area are Akgöl, Çağlayan and Görsökü formations. As aresult of a series of analyses , it was found that: Akgöl formation can only produce natural gas and has organic fades of C, CD andgas and has organic fades of BC, C, CD and D; and Gürsökü formation can CD and D.D; Çağlayan formation can produce oil and natural gaproduce low amount of gas and has organic fades of CD and D.
