| Zusammenfassung |
| Due to the closing of the subduction zone and the collision of the Arabian
and Eurasian plates, the High Zagros region has always been affected by a
wide range of tectonic variations. In this research, the Gharasu River basin,
which is located in the Kermanshah area, was selected as the study area, six
geomorphic indices were calculated, and the results of each one were divided
into three classes. Then, using the indices, relative tectonic activity was
calculated, and their values were classified and analysed in four groups.
Regions were identified as very high, high, moderate and low. In analysing
the results and combining them with field observations and regional geology,
the results were often associated and justified with field evidence. The
highest value is located on the Dokeral anticline in the crush zone in
Zagros. Most of the areas with high and moderate values of
Index of Active Tectonics (IAT) are also located in the crush zone in Zagros.
Crushing in this zone is because of the main fault mechanism of the Zagros
region. The result in this paper confirms previous
research in this region. At
the eastern end of the study area, the value of Iat is high, which could be
the result of the Sarab and Koh-e Sefid fault mechanisms. |
