“…In this region, Kürçer & Gökten (2012) found evidence for 2 M~6 earthquakes revealed in a paleoseismic trench and inferred a recurrence interval of ~5 kyr. These observations support our findings of very limited seismic activity along the Tuz Gölü Fault Zone during the Holocene.…”

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.

“…Nevertheless, when we recalculated their vertical displacement rate on the segment for the last 3 Ma, we obtained a very close result to our findings. According to Özsayın et al (2013), the vertical displacement rate of Kürçer and Gökten (2012) should be recalculated. They point out that Akhisar is located on a step-over zone where two segments of the TGFZ overlap and where a slip rate of 0.053 mm/year can thus be inferred for the eastern fault branch in the zone.…”

Geomorphological evolutionary history of the Melendiz River Valley, Cappadocia, Turkey

2019

The Melendiz River is located at the east of Tuz Gölü Fault Zone in western Cappadocia. In the central part of Melendiz River Valley, Ihlara Canyon attracts many tourists due to its landscape, cultural and archaeological values. The Melendiz Valley also encompasses geological and geomorphological features that exemplify the evolutionary history of western Cappadocia. In this study, the late Miocene-Quaternary geomorphological evolution of the Melendiz River Valley was investigated. The results indicate that a fluvial sedimentary sequence with ignimbrite intercalation was deposited during the late Miocene and early Pliocene. This was unconformably overlain by lacustrine limestone (Kışladağ Formation) of Pliocene age. The Pliocene lake regressed westward because of the changes in the tectonic regime and geomorphological processes during the late Pliocene (~ 3 Ma ago) and the initial Melendiz River developed on the lake bottom. During the Quaternary the Melendiz River developed under the control of both the neotectonic regime and the climate. This development provoked a 160-m-deep incision into the Pliocene sediments and the early Pliocene-Miocene ignimbrites below, giving birth to the Ihlara Canyon. In the proper valley of the Melendiz River, six strath terraces and Holocene flood plain record the incision process.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…Although our findings and observations in the Ecemiş Fault Zone are very local, taken together with other observations of first‐order tectonic structures in Central Anatolia [ Erol , ; Görür et al ., ; Yetiş and Demirkol , ; Koçyiğit , ; Dirik and Göncüoğlu , ; Koçyiğit and Beyhan , ; Çemen et al ., ; Koçyiğit et al ., , ; Jaffey and Robertson , ; Dirik and Erol , ; Koçyiğit , ; Özsayın and Dirik , ; Ocakoğlu and Açıkalın , ; Özsayın and Dirik , ; Doğan , ; Fernández‐Blanco et al , ; Genç and Yürür , ; Kürçer and Gökten , ; Yildirim , ; Çiner et al ., ; Gürbüz and Kazancı , ] and the Taurides, [ Cosentino et al ., ; Schildgen et al ., , , ], they contribute to some regional implications. In the interior of Central Anatolia, structural and GPS data reveal predominantly extension with localized strike‐slip faulting during the Quaternary [ Şengör et al ., ; Çemen et al ., ; Jaffey and Robertson , ; Özsayın and Dirik , ; Ocakoğlu and Açıkalın , ; Genç and Yürür , ; Doğan , ; Kürçer and Gökten , ; Özsayın et al ., ; Aktuğ et al ., ; Gürbüz and Kazancı , ], in agreement with our observations. Structural and geomorphic indicators of extension are especially prominent along the Tuz Gölü Fault Zone [ Çemen et al ., ; Koçyiğit , ; Kürçer and Gökten , ; Özsayın et al ., ; Gürbüz and Kazancı , ], which is a conjugate structure of the Central Anatolian Fault Zone.…”

Late Pleistocene intraplate extension of the Central Anatolian Plateau, Turkey: Inferences from cosmogenic exposure dating of alluvial fan, landslide, and moraine surfaces along the Ecemiş Fault Zone

Here we documented the vertical displacement, slip rate, extension rate, and geochronology of normal faults within a narrow strip along the main strand of the Ecemiş Fault Zone. The Kartal, Cevizlik, and Lorut Faults are normal faults that have evident surface expression within the strip. Terrestrial cosmogenic nuclide geochronology revealed that the Kartal Fault deformed the 104.2 ± 16.5 ka aged alluvial fan surface and the Cevizlik Fault deformed the 21.9 ± 1.8 ka old moraine and talus fan surfaces. Our topographic surveys indicated 120 ± 10 m and 13.1 ± 1.4 m surface-breaking vertical displacements along the Kartal and Cevizlik Faults, respectively. Accordingly, we suggest a 1.15 ± 0.21 mm a À1 slip rate and 0.66 ± 0.12 mm a À1 extension rate for the last 104.2 ± 16.5 ka on the Kartal Fault, and a 0.60 ± 0.08 mm a À1 slip rate and 0.35 ± 0.05 mm a À1
