Abstract: Gold mineralization in the Tanghuping Prospect was the target of the geophysical exploration. The mineralization shows close relation with geological structures and is accompanied by alteration. Sulfide concentrations in the altered zones were used to trace the mineralization by Induced Polarization(IP) method. Through laboratory and field measurements of some selected samples of the study area, their geophysical properties were studied carefully. After that by numerical calculation, a geophysical model was built. Six lines were designed to use dual-frequency IP sounding in the west of the surveyed area. Gradient, pole-dipole and reverse pole-dipole arrays were used to acquire the data. Interpretation of the processed data shows eight veins that demonstrate diverging and converging phenomena. Therefore east of the surveyed area is considered as most prosperous zone in the study area.
