“…Plate boundary interactions along the North Anatolian Fault during this neotectonic regime appear to have uplifted the northern plateau margin associated with the formation of a bivergent orogenic wedge (Yıldırım et al 2011), while lithospheric slab and upper mantle processes appear to have uplifted the southern plateau margin (Cosentino et al 2012;Schildgen et al 2012aSchildgen et al , 2012b. These crustal and subcrustal processes not only affected the topography of the CAP, but also likely influenced its climate by producing orographic barriers to moisture-bearing atmospheric circulation (e.g., Schemmel et al 2013), which probably had an important influence on deposition in interior sedimentary basins.…”

The Tuz Gölü Basin is the largest sedimentary depression located at the center of the Central Anatolian Plateau, an extensive, low-relief region with elevations of ca. 1 km located between the Pontide and Tauride mountains. Presently, the basin morphology and sedimentation processes are mainly controlled by the extensional Tuz Gölü Fault Zone in the east and the transtensional İnönü–Eskişehir Fault System in the west. The purpose of this study is to contribute to the understanding of the Plio-Quaternary deformation history and to refine the timing of the latest extensional phase of the Tuz Gölü Basin. Field observations, kinematic analyses, interpretations of seismic reflection lines, and 40Ar/39Ar dating of a key ignimbrite layer suggest that a regional phase of NNW–SSE to NE–SW contraction ended by 6.81 ± 0.24 Ma and was followed by N–S to NE–SW extension during the Pliocene–Quaternary periods. Based on sedimentological and chronostratigraphic markers, the average vertical displacement rates over the past 5 or 3 Ma with respect to the central part of Tuz Gölü Lake are 0.03 to 0.05 mm/year for the fault system at the western flank of the basin and 0.08 to 0.13 mm/year at the eastern flank. Paleo-shorelines of the Tuz Gölü Lake, vestiges of higher lake levels related to Quaternary climate change, are important strain markers and were formed during Last Glacial Maximum conditions as indicated by a radiocarbon age of 21.8 ± 0.4 ka BP obtained from a stromatolitic crust. Geomorphic observations and deformed lacustrine shorelines suggest that the main strand of the Tuz Gölü Fault Zone straddling the foothills of the Şereflikoçhisar–Aksaray range has not been active during the Holocene. Instead, deformation appears to have migrated towards the interior of the basin along an offshore fault that runs immediately west of Şereflikoçhisar Peninsula. This basinward migration of deformation is probably associated with various processes acting at the lithospheric scale, such as plateau uplift and/or microplate extrusion.

“…Depending on the geographic position with respect to the modern orography of the CAP and its margins, oxygen isotope ratios of present-day meteoric waters (δ 18 O mw ) on the plateau range from -12‰ to -8‰ with an isotopic lapse rate of ca. -3‰/km across the Taurides and Pontides (Schemmel et al 2013). Hence, modern δ…”

“…Based on our data, however, this relatively small topographic relief had no large effect on oxygen isotopes in precipitation on the plateau. The Oligo-Miocene oxygen (Schemmel et al 2013), calculated fossil meteoric water δ 18 O values for lake temperature of 20 °C using the fractionation equation of Kim and O'Neil (1997), and the average difference between fossil and modern meteoric water δ O mw than recent meteoric waters in this area (Table 3). This difference is in line with the magnitude of oxygen isotope fractionation related to present-day orographic rainout along the Pontide (ca.…”
