Abstract Both the phase IP and the polarization rate are important parameters which reflect IP characteristics of rocks or ores. Experimental work was carried out in a certain copper mine. Based on a comparison between the results of time domain IP survey and array phase IP survey, the real applying effects show that the phase parameter is more sensitive than IP to weak induced-polarization body. And the method of phase IP measurement is suitable for investigating work in the weak induced-polarization area.
