چکیده انگلیسی
The sedimentary information can be used to test two alternative tectonic models for the AlaÅehır Graben. In the first model, an E-W graben bounded by high-angle faults was active during latest Miocene(?)-Recent time, whereas earlier Miocene sedimentation was controlled by N-S faulting related to a N-S compressional stress regime. In the second hypothesis, the AlaÅehır Graben was initiated much earlier, in the Early Miocene and was then either continuously or episodically active until Recent. Our results, especially facies and palaeocurrent data from alluvial sediments, indicate that clastic sedimentation was controlled by mainly E-W faulting in a N-S stress regime. Assuming the Early Miocene clastic sediments are correctly dated, this supports the second (long-lived extension) model. However, rather than steady-state extension for ca. 15 Ma, the sedimentary evidence and regional context are consistent with a pulsed extension model, whereby initial Early to Mid-Miocene extension and related clastic sedimentation was followed by a second phase of extension in latest Miocene(?)-Pliocene time. The driving force of initial, Early Miocene extension was probably gravity spreading towards a south-Aegean subduction zone, whereas the inferred second extension pulse is seen as being triggered by westward “tectonic escape” of Anatolia towards the extending Aegean back-arc region.
