Induced-polarisation

http://drunkenwerewolf.com/?alkapone=%D9%88%D8%B3%D8%B7%D8%A7%D8%A1-%D8%A7%D9%84%D8%A3%D8%B3%D9%87%D9%85-%D8%A7%D9%84%D8%AB%D9%86%D8%A7%D8%A6%D9%8A%D8%A9&8f6=5a The induced polarisation probe measures the charge separation or ‘chargeability’ in porous, water-saturated, mineralised rocks caused by the passage of a low-frequency alternating current. The main cause of induced polarisation is a current-induced electron-transfer reaction between ions of an electrolyte in contact with grains of semi-conducting metallic minerals.

Principle of Measurement:

The integrated area under the voltage-time curve is a measure of chargeability.
