The effect of magnetic lineaments on the Ghezel Ozan River
The Ghezel Ozan River, the longest river system in the country, has responded to tectonic deformation thoroughly. In this paper the role of lineaments in making of active deformations via detection and characterization of geomorphic anomalies in the Ghezel Ozan River and correlation with magnetic lineaments is specified. In this study, the first fluvial anomalies have been identified on the satellite images and approved through DEM and field observations. Then these anomalies have been correlated with magnetic lineaments extracted from aeromagnetic maps and so the sub-surface active folds and faults have been recognized. Most ofthemagnetic lineaments in the Ghezel Ozan River basin have caused the geomorphic anomalies in the length of the river. The lineaments with trend of NW - SE have created various anomalies such as variations of channel pattern of the river, deflection of the river course and knick points in longitudinal profile of the river. The lineaments with trend of NE - SW have only straightened the course of the river.
