The collision history of the Arabian and Eurasian plate in SE Anatolia: paleomagnetic constraints on timing and kinematic evolution
SE Anatolia constitutes the northernmost extension of the Arabian Plate, and it is situated in an area where the subduction history of the southern Neotethys and the collision history of the Arabian and Eurasian plates are recorded continuously. 
It is one of the key areas to understand when and how the connections between Eastern Mediterranean and Indian Oceans were blocked. In Turkish literature, it is generally accepted that collision of Arabian and the Eurasian plates took place at the end of Middle Miocene. The collision in turn gave way to the development of the dextral North Anatolian and sinistral East Anatolian fault zones along which the Anatolian Block is escaping westwards towards the Hellenic Trench. 

The timing of the collision is based only on the total elimination of marine conditions in SE Turkey. However, the marine deposition occurred along two belts. The southern belt is located just south of the Bitlis-Zagros Suture Belt and the other one is located further in the north in the hinterland of the suture zone. 

It is the southern belt which is taken into consideration for the timing of collision. In addition to this, previous studies and models underestimated the role of the metamorphic belts and arc massifs, as well as Paleogene to Early Miocene events in the tectonic development of the region. 

The region possibly underwent back-arc extension in the Paleocene to Eocene period prior to terminal collision of the arc. Therefore, to better understand evolution of the region and the connections between Eastern Mediterranean and the Indian ocean, the Late Paleocene to Recent tectonic evolution of the region will be studied in detail. 

This involves the construction of an accurate time scale, and kinematic studies using fault slip data, remote sensing, seismic interpretation and paleomagnetism.
