The in‐loop pulse electromagnetic response of a stratified earth has been expressed in terms of an apparent resistivity‐ time plot using the PEM response over a homogeneous half‐space which is typically unipolar with monotonic decay. This half‐space response characteristic provides a unique relationship between Crone PEM channel amplitude and the apparent half‐space resistivity. The possibility to resolve a thin intermediate conductive and resistive layer with the in‐loop PEM system has been investigated. The system is well in shallow geoelectric mapping.
