An exploration method which uses either the decay of an excitation voltage ... or variations in the Earth's resistivity at two different but low frequencies ... 2, record 1, English, - induced%20polarization
Record number: 1, Textual support number: 1 CONT
When an electric current passing into the earth through ground electrodes is suddenly interrupted, a potential can be measured between these or nearby electrodes for some time after the current stops. This potential decays exponentially with time after the interruption. ... Known as induced polarization, this effect is associated with electrochemical reactions in the earth. 4, record 1, English, - induced%20polarization

Les minéralisations de sulfures relativement massives des skarns qui sont situées à la périphérie des minéralisations disséminées de sulfures de cuivre-fer de style porphyrique produisent des réponses électromagnétiques et de polarisation provoquée de plus forte intensité. 3, record 1, French, - polarisation%20provoqu%C3%A9e
Record number: 1, Textual support number: 1 OBS
L'expression «polarisation provoquée» (induite) vient du fait que la méthode est surtout utilisée pour détecter la polarisation électrique de surface des minéraux métalliques, laquelle est provoquée par les courants électriques qu'on envoie dans le sous-sol. 4, record 1, French, - polarisation%20provoqu%C3%A9e
