The use of Li-Oldenburg and smoothness constrained methods for inversion of IP and resistivity data in order to identify a polymetal deposit in Oshvand area

This paper presents the results of inverse modeling of induced polarization (IP) and resistivity data, acquired from Oshvand polymetal deposit area, using the Li-Oldenburg and Smoothness constrained algorithms. Oshvand deposit is located in northeast of Nahavand City in-Hamedan Province of Iran. To demonstrate the effectiveness of these algorithms, we have applied them on both synthetic and real data. In the synthetic case, good agreement is seen between the synthetic model and the estimated model, which is extracted from the inversion procedure. The inversion results of the real data example show good agreement between the results and geological evidences. It is also shown that twodimensional (2D) inverse modeling of IP and resistivity data provide invaluable information about the subsurface resistivity and chargeability distributions.
