The central Anatolia is comprises successor basins developed at the terminal phase of closure of Neotethys and collision of intervening continental fragments belonging to Gondwana (at the south) and Eurasia (at the north) along Izmir-Ankara-Erzincan Suture zone. The Intra-Tauride Suture Zone (ITSZ), however, developed between Gondwana derived that include Tauride and Kırșehir Blocks. These two sutures meet around the Haymana and Tuzgölü basins and gave way to complex evolution of associated Central Anatolian basins. In order to understand the deformation history of these basins we have conducted a comprehensive kinematic study that include determination of Anisotropic Magnetic Susceptibility (AMS) vectors of their Late Cretaceous to Recent infill. For this purpose more than 3000 samples from 112 sites were measured and analyzed. AMS as a paleomagnetic tool is very successful in determination of principal strain directions in low to moderately deformed sedimentary successions. The obtained results are compared with balanced cross-sections constructed from field and seismic data. The results indicate that the AMS vectors are highly correlated with the major structural trends in the basins indicating that the AMS is acquired during the deformation of the infill of these basins during Oligocene and onwards. This research was partly supported by National Science Foundation grants EAR-1109762, "Continental Dynamics: Central Anatolian Tectonics" (CD-CAT) to Donna Whitney and Christian Teyssier.

SW Anatolian tectonics are dominated mainly by emplacement of Lycian Nappes from north to south over the Beydaǧları platform during the early to middle Miocene, which followed by the development of the so called Fethiye Burdur Fault Zone (FBFZ). This fault zone is supposed to be a sinistral strike-slip fault zone that accommodated more than 100 km displacement between the Menderes Massif and the Beydaǧları platform during the exhumation of the Menderes Massif, mainly during the late Miocene. In addition, th...
Kinematics of Delice-Kozaklı fault zone (North Central Anatolia, Turkey)
Tokay, Bülent; Bozkurt, Erdin; Kaymakcı, Nuretdin; Department of Geological Engineering (2015)
The Central Anatolian Crystalline Complex (CACC) forms a part of Alpine orogenic belt in Turkey and incorporates three major massifs and several basins that developed during extension commenced by the Late Cretaceous. They were deformed during subsequent collision of Anatolide-Tauride Platform and Pontides. The deformation of the region has resulted in the break-up of the CACC along major deformation (fault) zones. The present study aims to test existence of one of these fault zones, namely Delice-Kozaklı f...
Kinematic and thermal evolution of the Haymana Basin, a fore-arc to foreland basin in Central Anatolia (Turkey)

Gondwana (Tauride/kirsehir blocks) and Eurasia (Pontides) derived continental blocks delimit the Haymana basin, central Turkey, to the south and the north, respectively. The boundaries of these blocks define the IzmirAnkara-Erzincan and Intra-Tauride Suture zones which are straddled by a number of Late Cretaceous to Oligocene marine to continental basins. The Haymana Basin is located at the junction of the IAESZ and ITSZ and comprises Upper Cretaceous to Middle Eocene basin infill deposited in response to t...
New zircon U-Pb LA-ICP-MS ages and Hf isotope data from the Central Pontides (Turkey): Geological and geodynamic constraints

The Central Pontides in northern Anatolia is located on the accretionary complex formed by the closure of Neotethyan Intra-Pontide Ocean between the southern Eurasian margin (Istanbul-Zonguldak Terrane) and the Cimmerian Sakarya Composite Terrane. Among other components of the oceanic lithosphere, it comprises not yet well-dated felsic igneous rocks formed in arc-basin as well as continent margin settings. In-situ U-Pb age results for zircons from the arc-basin system (tiangaldag Metamorphic Complex) and th...
Extensional tectonics of SW Anatolia in relation to slab edge processes in the Eastern Mediterranean

The tectonics of SW Anatolia is expressed in terms of emplacement of Lycian Nappes during the Eocene to Middle Miocene and synconvergent extension as part of the Aegean-West Anatolian extensional tectonic regime. Recent studies identified that there is a tear in the northwards subducting African Oceanic lithosphere along the Pliny-Strabo Trenches (PST). Such tears are coined as Subduction Transform-Edge Propagator (STEP) faults developed high angle to trenches. Hypothetically, the evolution of a STEP fault ...
