Take the Dias model expression IP effect of medium,In the case of a horizontal three-layer that middle layer is polarized. Fist calculate the apparent resistivity and impedance phase under natural electromagnetic source, Then extracte the IP parameter of amplitude ratio and phase difference from the data that frequency is same but chargeability is differ (m2≠0, m2=0), discussed the influence for IP sounding anomaly when the diffen section of resistivity. The last supply a test result over the lead zine mineral deposit.
