Electric and dielectric rock parameters were measured using an analogdigital computer for rapid evolution and data display. In common with many dielectrics, the imaginary part of dielectric constant established a circular arc when plotted against the real part at a series of frequencies. A conformal arc with the same relaxation time was obtained when the reactive component of impedance was plotted as a function of the resistive component. The data were verified on various rock samples of basalt, granite and quartzite in the frequency range 1Hz to 2kHz. Effects of rock pretreatments in water and in sodium hydroxide solutions upon their electric and dielectric parameters were studied.
