ABSTRACT
The purpose of this research is to investigate the organic geoch
emical characteristics of the Carboniferous Çelmeliler formation and the Permian Karadağ limestone in the south of Suğla Lake (Konya). The area is located in the Western - Central section of the Taurus Belt. The study area mainly consists of two units which are Upper Cretaceous Sülek complex at the base, and Middle Devonian-Quaternary sediments overlying the Sülek complex with a tectonic contact. Carboniferous Çelmeliler formation consists of shale and limestone. Permian Karadağ limestone contains thick bedded biolithoclastic and biomicritic limestones.The average total organic carbon (TOC) of the samples collected from the Çelmeliler formation is calculated as 0.06 %. The samples are generally derived from marine organic materials. Average vitrinite reflection (Ro) is 2.21 %. So that the unit is thought to be developed at the metagenesis zone according to the value given above. Considering the total organic carbon and hydrogen index (HI) values from the Rock-Eval pyrolysis, it can be concluded that the u
nit not a source rock for hydrocarbons but may be a source of gas. 0.057 % of total organic carbon mean value and an average value of 1.16 % vitrinite reflection are obtained within the measured section of the Karadağ limestone. These values indicate the catagenesis stage. Dominant organic materials in the samples are of marine origin.Key Words
