Özet: The study area is located on the Seyfe Fault Zone (SFZ) and Boğazlıyan Fault which is thought to be extension of Seyfe Fault Zone in Central Anatolian Crystalline Complex (CACC). The SFZ represents one of the most important regional-scale fault systems in Central Anatolia and has records the collision events that occurred during the closure of Neo-Tethys. The SFZ consists of WNW-ESE oriented dextral strike-slip faults. Whole rock and clay XRD and trace element data show that clay minerals collapse from hydrothermal water reaching the surface during deep tectonic activity. These fluids are migrated upward along shallow fragile deformation zones. The age of Rb-Sr geochronology of three different cataclastic zones as 1266, 1276 and 1488 m, showed the age of activity as 21.4 ± 0.57 Ma. According to this, the SFZ extends to the early Miocene and is consistent with both the relative age and the age data suggested in previous studies conducted within the CACC. Samples of 1266 m and 1276 m belonging to a possible thrust zone reveal that the closure of Palaeotethys and the beginning of Neotethys, which is accepted as Burdigalian period, occurred around 21 Ma ago in the Central Anatolian Crystalline Complex.
