A.C. Electrical Properties of Kolinite under Pressure-Pseudo Random Network Modeling

P054 A. C. ELECTRICAL PROPERTIES OF KOLINITE UNDER PRESSURE- PSEUDO RANDOM NETWORK MODELING Abstract 1 Few observations have been reported for the effects of pressure on the complex resistivity of rocks. The purpose of our study is to try to fit experimental data for kaolinite samples under a pressure up to ≈ 4. 5Kbar and ≈ 50% atmospheric relative humidity in the frequency range 10 Hz using a pseudo- random network model based on the renormalization group method. The model used for the grains is composed of surface impedance on the kaolinite grain surface due to the presence of water
