Özet

In the Central Taurides, the Sultan Mountains comprise in ascending order the Cimendere unit and the AkAYehir, Doganhisar, Cay nappes composed of metasedimentary sequences deposited from Cambrian to Tertiary. The overthrust of the Cay nappe on the Lutetian CeleptaAY formation representing the uppermost stratigraphic position in the Cimendere unit indicates that the latest nappe emplacement occurred during the Middle Eocene. The Oligocene and Miocene rocks are in post-tectonic facies in the west Central Taurides. The kinematic data from these nappes related to closure of the Neotethys reveal a top-NE shear sense in the northwest part and a top-SE shear sense in the southeast part of the Sultan Mountains. The Sultan Mountains are located in the north part of the Isparta Angle which was tectonically assembled by the Lycian, Hoyran-BeyAYehir-Hadim and Antalya allochthons on the Bey DaglarA +/- and Anamas-Akseki autochthons from the Latest Cretaceous to the Late Pliocene. The previous paleomagnetic data showed that the west and east subsections of the Isparta Angle were subjected to post-Eocene 30A degrees-40A degrees anticlockwise and clockwise rotations, respectively. In consideration of these paleomagnetic data, the kinematic data measured in the Sultan Mountains might be restored into approximately E-W-trending linear fabric associated with a top-E shear sense. These new kinematic data from the nappes in the Sultan Mountains disagree with the existing tectonic models that suggest N-S nappe translation over the Central Taurides during the latest Cretaceous-Middle Eocene. The alternative tectonic model for the Antalya nappes in the core of the Isparta Angle related to east-west compression suggests westward and eastward nappe emplacements on the surrounding autochthons. However, the new kinematic data presented here point consistently to a top-E shear sense in all tectonostratigraphic units in the Sultan Mountains currently located in the north part of the Anamas-Akseki autochthon.
