The mineralization shows close relation with geological structures and is accompanied by alteration. Sulfide concentrations in the altered zones w ere used to trace the mineralization by Induced Polarization(IP) method. Through laboratory and field measurements of some selected samples of the study area,t heir geophysical properties were studied carefully. After that by numerical calc ulation,a geophysical model was built. Six lines were designed to use dual-fre quency 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 phen omena. Therefore east of the surveyed area is considered as most prosperous zone in the study area.展开更多
