Failure mechanism by wrench faulting in Central Anatolia

The study area, where volcanism and tectonism are active at the same time, consists of the Cappadocia Volcanic Complex (CVC) in the middle, Tuzgol & uuml; on the west side, and Ecemis, fault systems on the east side. Remote sensing image processing method and derivation to aeromagnetic data were applied to identify the structural lineations that tectonically control the study area within the scope of the study. As a result of the lineation analysis performed in the west of the study area, 167 lineaments in the west, most of which are NW oriented, and 316 lineaments, most of which are NE oriented, were determined in the east. These findings are in agreement with the known fault orientations in the area. It is known that earthquakes greater than M > 4 occurred in these known faults during the neotectonics period, and they also have the potential to produce M > 6 earthquakes. In addition, the Tuzgol & uuml; and Ecemis, Faults' shearing effect relative to each other is an indication that a wrench tectonics mechanism has developed in the study area. With the remote sensing study and following the existing surface traces, two fault systems in opposite directions, the Tuzgol & uuml; Fault (-30 degrees) dipping counterclockwise and the Ecemis, Fault, clockwise (60 degrees) dipping, were determined. The orientation and locations of the faults could be determined by tilt transformation applied to the magnetic anomaly map of the study area. In particular, the effects of wrenching in the study area can be clearly observed in magnetic anomalies.

Automated summary

This study successfully identified the structural lineations of the study area through remote sensing image processing and derivation from aeromagnetic data, and found lineament distributions consistent with known fault orientations. The study also revealed the shearing effect between the Tuzgolü Fault and the Ecemis Fault, indicating the development of a wrench tectonics mechanism in the area. The orientation and location of the faults were accurately determined through tilt transformation of the magnetic anomaly map.
