Abstract
The paper studies the dispersion of dielectric permittivity and conductivity of carbonate rocks on the example of limestone mined in the south of Russia. It is shown that with increasing frequency there is a decrease in dielectric permittivity, and in the low- frequency region the basic mechanism of polarization is interfacial polarization. In turn, the conductivity increases with increasing frequency. Water saturation of the samples with distilled water leads to a multiple increase in the values of electrical properties studied in this work.
Keywords: dielectric permittivity, conductivity, frequency dependence, rocks, sandstone, dispersion
