Evidence is presented in this paper on the electrical nonlinear phenomena occurring above a certain charge density at the electrode plates (critical charge density, [Formula: see text]) for a serpentinite sample with dry electrode contact and a galena sample using moist electrode contact. The critical charge density for the serpentinite sample is [Formula: see text] [Formula: see text]. In terms of critical current density, it is [Formula: see text] at [Formula: see text] hz, or [Formula: see text] at 10 hz. The galena sample shows two critical charge densities, where one is [Formula: see text] and the other is [Formula: see text]. In terms of critical current density, it is [Formula: see text] at [Formula: see text] hz, or [Formula: see text] at 10 hz for the first critical charge. The concept of “critical charge and nonlinearity” is similar to that of “decomposition voltage” of electrodes immersed in an electrolyte. The decomposition voltage is a characteristic of conductors immersed in liquids, and it varies according to the type of conductor. It is thus possible that the nonlinear study of minerals could form a basis of a new geophysical technique, especially in borehole logging, for detecting not only the existence, but also the type, of minerals in the ground.
