The paper presents applying the edge detection methods on NW Iran. Iran is located in the Alpine Himalayan collision zone and is one of the areas where significant tectonic activities occur between the Caucasus and the Zagros Thrust Zone in the north. The area containing important areas of the Alpine-Himalayan orogenesis zone is controlled by a number of active and inactive faults. In order to determine the boundaries of these structures, the magnetic map of the region was constructed and edge detection methods (analytical signal, total horizontal derivative method and tilt angle derivative) were applied to the potential field data. With the interpretation of the magnetic data, the depth of deep sources caused to regional anomalies was found to be approximately 12.71 km whereas the depth of shallow sources was calculated as 1.25 km.  In addition to these, when taking into consideration geological background of the NW Iran, the main tectonic elements especially located in the eastern part of the study area are in good agreement with the constructed maps.
