Palaeomagnetic data in combination with palaeostress data and anisotropy of magnetic susceptibility orientations are utilized to develop a tectonic evolutionary model for the Early Tertiary part of the Ω (omega)-shaped Çankırı Basin (Turkey). The results reveal clockwise rotations in the northeast and anticlockwise rotations in the west and southeastern corner of the basin. The magnetic inclinations indicate a northward drift of the Çankırı Basin and support an indentation model for the Kırşehir Block. It is proposed that the Ω-shape of the Çankırı Basin was the result of indentation of the Kırşehir Block into the Sakarya Continent during northwards migration accompanying closure of Neotethys. It appears that the indentation started prior to Eocene and ended before Middle Miocene times.
