Abstract: To quantitatively reconstruct the kinematic evolution of Central and Eastern Anatolia within the framework of Neotethyan subduction accommodating Africa–Eurasia convergence, we paleomagnetically assess the timing and amount of vertical axis rotations across the Ulukıs¸la and Sivasregions.Weshowpaleomagneticresultsfrom ∼30localities identifying a coherent rotation of a SE Anatolian rotating block comprised of the southern Kırs¸ehir Block, the Ulukıs¸la Basin, the Central and Eastern Taurides, and the southern part of the Sivas Basin. Using our new and published results, we compute an apparent polar wander path(APWP)forthisblocksincetheLateCretaceous,showing that it experienced a ∼30–35◦ counterclockwise verticalaxisrotationsincetheOligocenetimerelativetoEurasia. Sediments in the northern Sivas region show clockwise rotations. We use the rotation patterns together with known fault zones to argue that the counterclockwise-rotating domain of south-central Anatolia was bounded by the Savcılı Thrust Zone and Deliler–Tecer Fault Zone in the north and by the African–Arabian trench in the south, the western boundary ofwhichispoorlyconstrainedandrequiresfuturestudy.Our new paleomagnetic constraints provide a key ingredient for future kinematic restorations of the Anatolian tectonic collage.
