Abstarct: Today, geophysical methods are widely used in the prospecting and exploration of mineral deposits. Using two or more exploratory methods together and combining them with other information such as geological studies can increase the probability of discovering and reaching promising areas. According to the evidence of mextallic and sulfide mineralization in the study area (exploratory range of old men), the use of airborne magnetometry, induction polarization (IP) and electrical resistivity (Res) to detect and detect potential minerals and perform Geological studies are of great importance. The study area is part of the volcano-plunge band of northern Torud- chah shirin that extends over 60 km in the northern section of the Torud- Moaleman Road and the west of the Torud-Shahrood road. The Torud- Moaleman Area has many faces of volcanic rocks with a combination of dacitice and pyroxene andesite as volcanic lava, agglomerate, volcanic breccia, sandy tuffs, and facies of zeolite. Mineralization In the exploration area, malachite is often accompanied by iron oxide as veinlet and vein. Mining is probably due to severe fault in the region.
In this research, first, the airborne magnetic method was used to determine the Trend and stretch of mineralization, and then in the sequential phase, to identify susceptible and suspect areas for copper mineralization in a wide range of areas, first, from the rectangular array, which is one of the most common formations for the transition and Initial identification in exploratory work was used. Given the geological evidence in the area and the existence of outcrops, two rectangular array were designed and implemented. In the next step, three dipole-dipole profiles of DD150, DD250, and DD450 were taken to verify the areas determined at the transitional stage. Then, the induce polarization and resistivity data measured using Res2DINV and ZondRes2D software’s have been processed and modeled using two-dimensional smooth surface inversion. Finally, baxsed on the results, 8 point was proposed for drilling.
