Stratigraphic correlation of the Neogene basins in southwestern Anatolia: Regional palaeogeographical, palaeoclimatic and tectonic implications

The extensional intramontane grabens that formed in southwestern Anatolia in the Late Cenozoic bear the unique tectono-sedimentary, palaeontological and palynological record of a region that underwent rapid transition from the last compressional pulses of the Alpine orogeny to the tectonic phase of orogen collapse and the onset of neotectonic regime. The change in tectonic regime was accompanied by regional climatic changes, recorded by the sedimentary environments of the basins and evidenced by palaeontological and palynological data. The late Early to mid-Middle Miocene was characterized by a warm and humid subtropical climate with densely forested wetlands. The late Middle to Late Miocene witnessed a change to arid climatic conditions, with grass-dominated steppe ecosystems. The Pliocene climate was warm and humid, with savannah-type open habitats.
