Effects of Caspian (Khazar) Fault Activity on Geomorphology of Qaemshahr area

The Caspian (Khazar) fault is the boundary between the Caspian plain and Alborz Mountain. As a major tectonic feature، this fault may be considered as the northern mountain front fault of the Alborz Range. Subsidence of the Caspian Sea in north، uplift of the Alborz Mountain، and its over thrusting on southern part of South Caspian basin has occurred along the Caspian fault. In this paper، a segment at the fault which is located between longitudes 52° 30׳ and 53° 00׳ - in the northern part of geological map of Qaemshahr - is considered as a segment that does not outcrop. This paper introduces the general structural and morphotectonic characteristics of this zone and describes the characteristics of the active anticlines (growing folds) and morphotectonic effects in this zone such as effects on rivers.
