Organic geochemical characteristics of the Carboniferous and Permian units in the south of Sugla Lake (Konya) [Sugla Golu guneyinde (Konya) Karbonifer ve Permiyen yasli birimlerin organik jeokimyasal ozellikleri]
Abstract
The purpose of this research is to investigate the organic geochemical characteristics of the Carboniferous Celmeliler formation and the Permian Karadag limestone in the south of Sugla 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 Sulek complex at the base, and Middle Devonian-Quaternary sediments overlying the Sulek complex with a tectonic contact. Carboniferous Celmeliler formation consists of shale and limestone. Permian Karadag limestone contains thick bedded biolithoclastic and biomicritic limestones. The average total organic carbon (TOC) of the samples collected from the Celmeliler 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 unit 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 Karadag limestone. These values indicate the catagenesis stage. Dominant organic materials in the samples are of marine origin.
