  • 4.4 Electrical conductivity of minerals and rocks

    The soils, unconsolidated sediments, and rocks of the crust of the Earth are principally composed of silicate minerals, which are electrical insulators. Their resistivities are typically greater than 1010Ohm-m and they carry no current. (At high temperature these minerals begin to dissociate and current can be carried by their ions.

    If the resistivity of the rocks is everywhere uniform, then the current sheet is uniform as well. However, if, for example, an appropriately- oriented long shear zone of 1 000 ohm-metres (S-m) lies in a host of 10 000 S-m, then the current sheet will be deformed and ten times as much current will flow in the shear zone as in the host rocks.

  • Geophysical Methods

    Usually these surveys are very informative for determining rocks because you end up with both an IP and resistivity map at the same time, allowing both measurement types to be interpreted. It is therefore important for mineral exploration, as sulphide minerals – including those hosting gold, silver and copper, generate a very large IP signature. This is especially useful when the metal ...
