Abstract The CSAMT method was used to conduct exploration of concealed ore bodies in the Shishi-Beiye ore district of Xin'an County, Henan Province. The results show that this method can be used to perform inversion of paleo-landform of Ordovician limestone, infer occurrence space of ore-bearing rock series, and predict potential resource quantity of bauxite. With this method, the exploration depth is relatively great, thus meeting the requirement of deep bauxite detection. The resistivity contour lines of the section of CSAMT can quite clearly reflect the attitude of strata, and hence the resistivity values can be used to divide strata.
