Abstarct: Sanandaj-Sirjan zone as a deformation belt with north-west-south-east trend has dynamic structures due to the convergence of Arabian-Urсьh plates in Iran's territorial part. Here, with the study of land development associated with the activity of the Dehagan fault 60 km southwest of Isfahan, using the combination of remote sensing knowledge and field observations, the structure of the region was analyzed. The inverse fault of the dehagans along the north-west-south-east and the slope to the south-west has a right-movement component. Rose Diagram of all fractures and the process of laminations in the region derived from remote sensing studies on satellite images, indicates the geometric coordination of the inverse fault of the dehajans with the folding of the formations. Also, areas with high fracture severity are approximate in areas with karst springs in the area. According to the results of this study, significant evidence in young sedimentary units indicates the activation of deformation and active non-structural deformation in the region. The upper Cretaceous limestones, which are exposed throughout the fault zone of Dehaghan, have been affected by the fractures due to this fault to the extent of the karstised, and there are the presence of dry karst valleys and small and large carneys in all The calcareous limestone of the region is observed. In addition, several karstic springs have appeared along the fault zone. In any case, the absence of a large karstic spring, as well as important morphological complications (such as crater, blocked bezel, deep carnephins, and plaque) Development is relatively unlikely in the region.
