Firstly, a multi-layered numerical model of a polarization body was established in sense of physical and mathematical derivation. The polarization field generated from the model was the stack of individual fields generated from multi-layered polarization units. The equation for eliminating strong shallow polarization anomalies from the sounding data was derived based on the principle of multiply eliminating the fields of individual polarization units. As a result, the deep polarization anomalies were prominent. The processed sounding data was used to quantitatively calculate the depths to the tops of deep altered zones of golden mineralization.展开更多
