Carbonates of Miocene Mersin Basin, Turkish Mediterranean Sea

Mersin Basin is located at the wedge of Middle and Eastern Taurides of SE Anatolia bordered by Ecemis fault zone to west and by Missis High to east. Two major tectonic phases took palace in evaluation of the Miocene basin. Lower to Middle Miocene age NE-SW oriented normal fault which created the Adana-Mersin basin and Missis Uplift began to develop at the end of the Miocene and Lower to Middle Miocene Basin was divided into two seperate basins which are Adana-Mersin and Iskenderun basins.

Adana-Mersin basin consists of fluvial to deep marine clastic and carbonate sediments. The basement of the Neogene section of Adana Basin has an irregular morphology; the depressions are filled by conglomeratic units. This unit overlain transgresivly by the major reef complex of Lower to Middle Miocene Karaisali Formation, mainly reefoidal and biostromal carbonate sediments progressively younger towards the basin margin. The first commercial oil discovery was made by Mobil in 1960 from the Burdigalian- reefal carbonates and the underlying fractured pre-Miocene carbonates in the Bulgurdag oil field. This carbonate section is also present in two wells (Degirmen-1, Mersin-1) located at the onshore margin of the Mersin basin. This reefal complex is interfingered and overlain by marly units of Köpekli Formation which have source rock potential. These reefal reservoirs can be charged not only by maturation of Köpekli source rock but also underlying Paleozoic and/or Mesozoic source rocks.
