The Kösdağ Metavolcanics (KMs) in the southern Central Pontides are exposed between the İzmir-Ankara-Erzincan Suture Belt in the south and the Sakarya Composite Terrane in the north. They comprise an approximately 40-km-long tectonic unit, bounded by the splays of the North Anatolian Transform Fault in the north and the Kızılca Thrust in the south. The basement of the unit mainly consists of metabasalts, metaandesites, and metarhyolites, with well-developed blastomylonitic textures, which are interlayered by recrystallized pelagic limestone and chert.

The Güneyce Formation is well exposed in the Lake District of southwestern Turkey. It was deposited in the early Miocene in the Neotethys ocean and contains a large variety of trace fossils. The following ichnotaxa were recognized: Chondrites intricatus, C. targionii, Cosmorhaphe isp., Helminthopsis isp., Helminthorhaphe flexuosa, Lorenzinia isp., Naviculichnium marginatum,...

Felsic intrusive rocks within the Central Anatolian Crystalline Complex provide a window into the geodynamic processes in operation during the final closure of the Neotethys Ocean. Previous studies were largely restricted to the calc-alkaline granitoids, and the structural and petrogenetic relations of syenitoids are poorly studied.

The Çangaldağ Complex in northern central Turkey is one of the main tectonic units of the Central Pontide Structural Complex that represents the remains of the poorly known Intra-Pontide branch of the Neotethys. It comprises low-grade metamorphic rocks of intrusive, extrusive, and volcaniclastic origin displaying a wide range of felsic to mafic compositions.
