The apparent resistivity of dual-frequency electromagnetic sounding is a new method of geoelectric measurement with dual-frequency electromagnetic wave. By analysing apparent resistivtiy curves of various geoelectric sections, the present paper has proved the practicability of this method.Being the monodrome function of electromagnetic response, the apparent resistivity can objectively describe electric characteristics of the geoelectric section,suppress the interference of background field, and highlight geoelectric anomalies. Its capacity for distinguishing strata and its characteristics can meet the requirements of sounding.
