“…In other words, the incision rate between 5 and 2.5 Ma was computed as 0.12 mm/ year, then post-2.5 Ma, the incision rate became slower at 0.04 mm/year. Doğan (2011) investigated the Kızılırmak River incision, where he concluded that the Kızılırmak River incised its valley by 160 m during the last ~2 Ma of its evolution. Furthermore, by using terrace sequences and basalt ages, Doğan (2011) proposed a 0.08 mm/year incision rate with a maximum of 0.12 mm/year between the late Early and Middle Pleistocene.…”

“…Our new Ar/Ar plateau age on the groundmass of the Evren Ridge basaltic lava reveals an age of 1.85 ± 0.07 Ma. It was also previously dated to 1.92 Ma by Doğan (2011). According to this age, an incision/erosion rate is calculated to be 106 m in about 2 Ma (Figure 8).…”

“…The other acceptable result was obtained from a 96-ka Quaternary basalt (Doğan 2011). In his work, Doğan (2011) distinguished 4 basaltic flows forming Kızılırmak terraces, and suggested that the 96-ka basalt is the youngest flow in the Kızılırmak area.…”

“…The erosion rate of 'fairy chimneys' was calculated to be between 2.30 and 3.28 cm/kyear (Sarıkaya et al 2007). River incision rates have never been calculated in the CVP, except the incision of the Kızılırmak River by Doğan (2011).…”

“…The plateau uplift causes variations in erosional patterns, as is the case in Central Anatolia. River incision has becomes important in the last 2 Ma from the Kızılırmak River carving out about 160 m (Doğan 2011). Apart from river incision, tectonic uplift causes an increase in erosion (Montgomery & Brandon 2003).…”

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

In this study, we investigate the geochronological, geochemical and isotopic characteristics of two travertine sites surrounded by Quaternary eruption centres in central Anatolia with ample palaeo-eruption records. High-resolution carbonate precipitation records, revealed by U-Th dating, are clustered around 5-35, 60-100 and 120-170 ka and are well correlated with the dataset on eruptions as well as the position of fractures related to the volcanic centres. Syn-eruptive carbonate precipitation seems to occur due to the circulation of CO 2-rich fluids along the extensional fracture systems aligned tangentially to the related volcanic conduit and, therefore, the study of this system could be an alternative technique for the reconstruction of palaeo-eruptions. δ 18 O values of the studied travertines are within the range of meteogene fluids. Oxygen isotope compositions at around 130 ka match well with Glacial Termination II that is also recorded by climate proxies in various cave and benthic deposits throughout the world. It is likely that the studied carbonates were precipitated under similar fluid circulation conditions which are represented by a high rate of dilatation followed by a meteoric water influx into the extensional fractures.
