Neogene tectono-sedimentary development of the western margin of the Cankiri Basin, central Turkey

Abstract

The Neogene succession in the western margin of Cankiri Basin is fragmented by a NNE-trending tectonic sliver having normal faulted western and thrusted eastern margins. This newly recognized E-vergent sliver was created by the NW-SE compression due to the North Anatolian and Kirikkale-Erbaa Fault zones following late Pliocene, accommodating the internal deformation of the Anatolian plate. Determinations of the Kilcak, Kumartas and Hancili formations on both sides of this tectonic sliver invalidate the stratigraphical, structural and basin evolution models previously proposed by Kaymakci.
