Resistivity and Induced Polarisation Surveys – Geology …

Quartz, the most common mineral in epithermal veins and associated breccia, has a very high resistivity relative to other minerals. For this reason, quartz-rich zones that may host gold mineralisation, show up in surveys as zones of high resistivity or low conductivity.

With the first relation, resistivity of a rock of known porosity can be calculated relative to fluid resistivity, and with the second, the effect of pressure of up to 10 kb. For a rock composed of conductive minerals, pressure at first decreases resistivity sharply and, then, has almost no effect.

Electrical resistivity of geologic materials

Of all the geophysical properties of rocks, electrical resistivity is by far the most variable. Values ranging as much as 10 orders of magnitude may be encountered, and even individual rock types can vary by several orders of magnitude.
