Northwest Anatolia has a special importance in terms of the geological evolution of Turkey because there are several suture zones reflecting the occurrence of different oceans between late Palaeozoic-early Tertiary time. These oceans were the Palaeo-Tethys ocean and the Karakaya basin which both closed in Jurassic time, and the Neo-Tethys ocean which closed in late Cretaceous-early Tertiary. Following these events, the neo-tectonic period started. A north-south extension in the early Miocene occurred in western Turkey, and later, in the late Miocene, the North Anatolian Fault formed a diffused strike-slip boundary in northwest Anatolia. The vicinity of the Paşalar excavation area in northwest Anatolia has been mapped and the stratigraphic units described. The Karakaya Complex belongs to the Karakaya basin and is made up of sandstone with limestone, chert and spilite blocks. The Manyas Group relates to the closure of the Neo-Tethys ocean and is made up of marble and schist. The Çatalda |
