  • 44 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 1010 Ohm-m and they carry no current. At high temperature these minerals begin to dissociate and current can be carried by their ions.
