    Chargeability¶. The following tables (from Telford et al, 1976) provides a very general guide to possible chargeabilities of materials. One reason that in-situ chargeabilities tend to appear lower than laboratory values is that large volumes of mixed materials are involved in field measurements.

    Resistivity of Earth Materials. Although some native metals and graphite conduct electricity, most rock-forming minerals are electrical insulators. Measured resistivities in Earth materials are primarily controlled by the movement of charged ions in pore fluids. Although water itself is not a good conductor of electricity, ground water

  • Electrical resistivity of geologic materials

    In this chapter, electrical properties of geologic materials are discussed separately for metallic minerals, rocks, soils, and electrolytes (ground fluids). What is resistivity? Electrical conductivity (or resistivity) is a bulk property of material describing how well that material allows electric currents to flow through it. Consider current

  • Electrical Conductivity — GPG 0.0.1 documentation

    Electrical current within a rock will choose not to flow through the pore-space if the rock forming minerals are more conductive. This occurs frequently in ore-bearing rocks due to the presence of metal-oxides (magnetite, illmenite, specular hematite), metal-sulphides (pyrite, pyrrhotite, galena) and native metals (gold, silver, copper).
