Tectono-stratigraphic constraints from southern Anatolia and Cyprus on the Neogene evolution of the Cyprus Arc
A major EurAf (Europe-Africa convergence) program focus area of ISES is Turkey/Anatolia, a region with a geological history that is inevitably related to the collision between Africa-Arabia and Eurasia. 

Schematic representation of evolution of slab detachment, roll-back and STEP faulting in the Cyprus arc
The proposed project focusses on the Cyprus arc region in south-central Anatolia and on Cyprus, and aims to reconstruct the Neogene deformation and sedimentation history of this largely unstudied, but geodynamically essential region. A recently proposed scenario concerning the evolution of the subducted slab in the Arabian-Eurasian collision zone and the eastern Mediterranean region suspects a combination of slab roll-back, slab detachment and STEP faulting, ultimately forming the Cyprus arc. 
An approach integrating remote sensing, structural, sedimentary, stratigraphic and paleomagnetic (field) analysis is proposed to reconstruct the vertical, horizontal and rotational motions associated with the Cyprus arc to test and further develop the geodynamic scenarios that explain late-orogenic evolution of the closure of the Neotethyan Ocean.

This project links with many other PhD and Post-Doc research projects that are already actively studying the tectonic, paleoceanographic and geodynamic history of the eastern Mediterranean region within the contect of the ISES EurAf program.
