Abstract: The geology of the Çankırı Basin has been studied using multi-source data including satellite images, aerial photos, gravimetric data and seismic sections, which are subsequently used to generate maps and a 3D model of that part of the basin covered by the seismic sections. From the compilation, three different phases of deformation are recognized. The earliest phase is characterized by thrusting during the Early Tertiary. The second deformation phase is characterized by extensional deformation associated with normal faulting in the latest Early Miocene to Middle Miocene. The third, and the last, phase is characterized by compressional deformation manifested by inversion of some of pre-existing normal structures that has been taken took place since the Late Miocene. Finally, the constructed model and the maps helped to better understand the 3D geometry and tectono-sedimentary evolution of the Çankırı Basin and the collisional history of the Sakarya Continent and the Kırşehir Block along the İzmir-Ankara-Erzincan Suture Zone.
