Abstract

Relationship between the electric conductivity of mica minerals and content in them of interlayer cations is studied by researching the geoelectrical properties of dielectric materials. Conductivity isotherms have been obtained for biotite, phlogopite and muscovite at 200 and 950°C, respectively. For phlogopite and muscovite, decrease in conductivity with increasing in sodium content has been found. This is due to the fact that the radius of the sodium ions are smaller than potassium ones that results in a significant compression of a space around the sodium interlayer, which complicates migration of ions. The availability of potassium in the mineral results in a higher conductivity. It is concluded that the correlation between sodium and potassium in mica, depending on the physical and chemical conditions of their genesis, determines the magnitude of their conductivity.
