5. Part D. Induced Polarization, a Review

Abstract
Investigations into the causes of induced polarization have shown that the largest effects are due to the presence of electronic conducting minerals in the pore system of the rocks. Theoretical studies into the charge transfer reactions involved when current is sent through such mineralized rocks have led to some simple rules concerning the time or frequency structure of the induced polarization effects. There are a few indications that at very low frequencies or at long time scales, deviations from these rules occur that may provide further parameters for evaluating induced-polarization effects.
