Dielectric Relaxation and Rock Geophysical Characteristics
Abstract
Existing impedance equipment has been modified to measure the complex impedance of rocks in the frequency range of .05 to 2,000 Hz. Impedance measurements have been carried out on samples of Dresser basalt, Charcoal granite and Sioux Quartzite. The resulting series reactance and resistance values have been displayed on an Argand diagram and also, plotted against the logarithm of frequency. Adherance of the data to the circular arc plot is clearly evident. Qualitative effects on impedance were found for both temperature and rock humidity. A method was developed to correct rock impedance data for electrode polarization effects. A technique was developed to extract the rock dielectric constants from the impedance parameters. The real and imaginary parts of the complex dielectric constant for basalt have been displayed on a Cole-Cole plot and also, plotted against the logarithm of frequency.
