Organic Facies Characteristics of the Pliocene Coaly Units, Central Anatolia, Ilgın (Konya/Turkey)

Pliocene units are composed of sandstone, siltstone, marl, mudstone and coal in the region. Organic matter in these units have generally low hydrogen index values and high oxygen index values, mostly characteristics type III kerogen (partly type II kerogen). Total organic carbon values are between 0.03-53.4% in the formation. Tmax values vary between 392 and 433°C. Organic facies type C, CD and D were identified in the studied units. The organic matter is terrestrial, partly oxidized/oxidized/highly oxidized, decomposed and reworked. Organic facies C and CD are the “gas-prone” facies but organic facies D is nongenerative.
