Paleomagnetic investigation of the Miocene - Quaternary volcanic rocks between Varto-Tunceli

Abstract

After collision between the Arabian and the Eurasian plates, Anatolian plate began to move westward, along the East Anatolian Fault Zone (EAFZ) and North Anatolian Fault Zone (NAFZ). NAFZ and EAFZ meet with the Varto Fault Zone (VFZ) and form a triple junction in the 10 km northeast of Karliova. In order to determine the tectonic evolution of Karliova Triple Junction (KTJ) and it's around, paleomagnetic samples were collected from the volcanic rocks, whose ages range from Miocene to Quaternary times. Our paleomagnetic results, obtained from the Karliova - Varto - Solhan region are indicate that there are counterclockwise (CCW) rotation in the regions closer to the NAFZ and EAFZ. different rotations are seen in the east of the KTJ, both western and eastern parts of the Varto Fault Zone. Also there is a remarkable change in the tectonic regime of the Tunceli - Elazig province in the Miocene - Pleistocene time interval. Copyright © Congress of Balkan Geophysical Society, BGS 2019.
