The high resistivity layer shall not be infinitely great or close to surface, otherwise the layer will prevent the current entering the anomaly body and no anomaly will be produced.
There is no high conductivity layer between the two plate suture zones, on the other hand the crust is an integrated high resistivitybody.

The induced polarization anomaly is character of high in chargeability and low in electrical resistivity which is consistent with the electrical property of copper ore-body.
