Abstract—Electrical resistivity (RS) and induced polarization (IP) methods have an important role in exploration of disseminated metal and sulfide mineralization zones. In the exploration geophysics, in order to minimize the error in determining the dimensions and depth of anomalies, two integrated geophysical methods are common. This paper investigates the capability of the electrical resistivity and induced polarization methods in order to delineate the presence of minerals containing metalore deposits. The presence of metal ore deposits in rocks generally lowers the resistivity. Ions in the vicinity of metallic grains in rocks increase the chargeability of the rock when measured using IP method. Since it is possible to define any arbitrary structure in forward modeling, it was used to generate data. Some noise was added to make the data look like real observed data. Also, a computer program was written in MATLAB for performing inversion modeling using finite element method. Finally, this program was applied to determine the limits of the existent anomalies based on the real data collected from Bardeskan region (Khorasan Razavi province in Iran) and to be sure, it was compared with the RES2D INV that the results were satisfactory.
