| Zusammenfassung |
| Collision between the Arabian and the Eurasian plates initiated in Serravallian age (12-13 Ma). This collision caused a large plateau formation about 2 km elevation. Result of the collision, Eastern Anatolian Region still continious to evolve as a young mountain belt. East-West trending folds, thrust faults and strike-slip fault systems were developed due to the compressional tectonic regime in the region. After the formation of the plateau, volcanism took place occupying large areas. The thickness of this volcanic series reaches to 1 km.
In order to determine tectonic evolution (rotational and latitudinal movements) of the North of the Lake Van, oriented paleomagnetic samples were collected from the volcanic rocks whose ages has already been determined from radiometric methods and ages range from Miocene to Quaternary times. The origin of the collected palaeomagnetic samples from different volcanic series were came from volcanic centers in this region such as the followings: Aladağ, Tendurek, Etrusk, Girekol Mounths and Pliocene plate basalts.
Our preliminary results indicate that most of the clockwise and anticlockwise rotations and deformation occured during the Miocene- Pliocene times. However, in Pleistosene time there weren’t any considerable rotations and deformations. The main reason of the deformations were related with the collision between the Arabian plate and the Eurasian plate and accomodated by regional faults and westards escape of Anatolia. Our results are in good agreement with previously done palaeomagnetic studies, seismological and GPS data in the region. |
