Electrical Properties of Rocks
- Electrical conduction
The movement of electron or electrically charged particles through a medium.
Any substance containing free ions that make the substance electrically conductive. The most typical electrolyte is an ionic solution.
- Fermi level
The highest energy of occupied states in a solid at 0 K. The Fermi level in conductors lies in the conduction band, in insulators it lies in the valence band, and in semiconductors it falls in the gap between the conduction band and the valence band.
- Stern layer
One of the two electrically charged layers of electrolyte ions: the layer of ions immediately adjacent to the surface and the layer in the neighborhood of a negatively charged surface.
The interpretation of electromagnetic data obtained from the electromagnetic (EM) induction method requires knowledge of electrical properties of rocks comprising the Earth’s interior. The electrical properties of rock are now widely used in electrical conductivity...
