The Evaluation of Saravan Fault Activities in Iran on the Basis of Geomorphologic Evidences


Saravan fault in Iran is a reverse fault with the dextral strike– slip component. In this paper, we studied the Current Activity Effects of this fault on Regional Structural Geomorphology. This study includes not only the new Neotectonic evidences but also parameters such as mountain front sinuosity 1, rate index (V) , Hydraulic Gradient Index of Stream (SL) that has carried out by field sampling , using satellite images , topographic maps and SRTM data. The mean calculated values from geomorphologic indices of meanders of mountain front, the ratio of valley bottom over its height and the ratio of V are 1.76, 0.98, and 0.77, respectively. These values indicate the high tectonic activities in Saravan region. The existence of Geomorphologic Evidences such as moved channels has proved Dextral Fault for the youngest stage of performance called Post-Cenozoic. It is found by the study of regional morph tectonic units such that the whole region is active tectonically, and Saravan fault where located in the middle part has higher activity than its two northwestern and southeastern extremes.
