The Induced Polarization Logging tool is a multi-parameter tool for hard rock mining application and uranium exploration. Chargeability of the formation is used to detect sulfide bearing rocks, similar to pyrites and other magnetic minerals. The tool uses a 16 and 64 array electrode spacing and passes an alternating current through the formation, resulting in a measure of chargeability.

The tool records four different parameters simultaneously in one pass of the borehole:. natural gamma, spontaneous potential, single point resistance, and induced polarization.  The natural gamma detector is optional.
