Abstarct: Since most copper deposits are porphyry; the optimal exploration of porphyry deposits in Iran has a great importance. In exploring this type of ore deposits, geophysical and geological surveys provide researchers with useful information on determining the location of mineralization, the separation of vast zones from the field and the location of exploration boreholes. One of the major problems in the exploration of mextal minerals, especially porphyry copper deposits, is the existence of high-induced polarization (IP) zones in geophysical modeling sections; which In drills, they appear as low-grade copper and mainly pyrite-like zones. This thesis is defined for geophysical data modeling consistent with geological facts and providing a method for improving the interpretation of geophysical data in Kalat-e-Reshm (Semnan) area. Available data include 11 Resistance and Induced Polarization (IP) profiles with dipole-dipole arrays and N45E process at intervals of 50 meters from each other and an electrode distance of 20 meters and an approximate length of 600 meters, that only the fourth profile has north-south trend. Due to the limited number of pages and explanations in this text, only 2 IP/Res profiles were explained and 84 magnetometric profiles with a north-south trend of 3000 meters long and 50 meters apart were taken from each other. On each profile, the stations were taken at a distance of 20 meters from each other. Initially, two- and three-dimensional inverse modeling was performed on IP / Res profiles data with RES2DINV, RES3DINV and VOXLER software. Magnetization data was performed with the MAG3D software, and the interpretation has taken. The mineralization is formed in the Andesitic and altered units; which has been accompanied with high loading rates as well as medium to relatively high special resistance in most areas, And so it has been identified. Using the results of interpretation of IP/Res data modeling, as well as maps derived from magnetometric data and interpreting the modeling of magnetized data, mineralization areas were identified in the region. baxsed on these results, a suitable site for drilling in order to achieve copper mineralization is proposed in depth.
