Abstarct: Faults are one of the controllers of mineralization in most deposits and play an essential role in trapping minerals and identifying the concentrations of them. In fact, faults and fractures are a way for hydrothermal fluids to penetrate, and mineralization often occurs in fault zones, fractures and their intersections. Detecting faults in a region and determining their density and mechanism of structure plays an important role in mineral exploration. The purpose of this research is to investigate the relationship between faults and copper mineralization in Moalleman region in the south of Damghan to Abbas Abad area in the east of Shahrood, which has significant copper potential. In order to identify fault structures and prepare an integrated fault information laxyer of the entire study area, geological, remote sensing and airborne magnetics data were used. To detect faults from the airborne magnetic data, first the initial processing was done on the data and then by applying different filters such as reduction to the pole (RTP), upward continuation and downward continuation of the magnetics field, vertical and horizontal derivatives and local phase filters; position and spread of magnetic anomalies and magnetic lineaments were determined. Also, the faults and lineaments were identified from remote sensing and geological data, and the final a fault map of the entire region was prepared by combining these laxyers. In order to further analysis the extension of faults and lineaments, Rose diagram software was used and the faults were checked for the entire region and three sub-regions, and the main density of the faults was determined. In this way, the main extension of the faults are in the azimuths of 70 to 85 degrees and the extension is perpendicular to this direction. At the end, a map of faults, magnetic anomalies, active mines and copper mineral indices in the region was prepared. According to the main trend of the faults as well as the location trend of active mines and magnetic anomalies, it can be concluded that the main mineralization is affected by the main faults of the region, such as Troud and Anjilo, with the northeast-southwest direction and the faults perpendicular to the main faults. In this way, it can be said that in areas where there are no rock outcrops and mineral indices, the magnetic anomalies are a good sign to prospect for new mineral resources in the region, which requires in-depth investigations with more resolution data. The results obtained from this research in the whole region confirmed the results of the studies of smaller areas in this region and it can be said that the role of faults in copper mineralization is important and the main factor.
