To provide detailed geophysical information for the deep mineral exploration of lead-zinc ore in the external area of Xitieshan mineral deposit, a combined geophysical method of highpower induced polarization (IP)and transient electromagnetic method (TEM ) has been utilized successfully in Xitieshan area where the ground condition is poor and the terrain is very tuff. The accurate IP measurements carried out is due to a special processing method to reduce the contact resistance, thus leads to the transmitting current up to 10A. At the south extension of line 28, a low resistivity and high induced polarization abnormal has been discovered. Combined the geology research result outside of the area, the abnormal could be considered caused by the deep lead-zinc ore body. It provides very valuable evidences for the further deep mineral exploration in the area.
