Abstract : The measured frequency dependence of the dielectric constants and conductivities of water-containing rocks is explained qualitatively and partly also quantitatively, by means of interfacial polarization and by a theoretical consideration on dielectric losses. The relations between the relaxation times of the rock - water system and water content obtained by experiment, and the relations between conductivity and water content of the examined rock samples are given. Furthermore, the dependence of the electrical parameters on the rock fabric is shown and a method is described for measuring by an electrical process, the water content and porosity of a low-porous rock sample.
