Outline
The electrical conductivities of the iherzolite were measured by virtue of SARLTON-1260 frequency and phase impedance spectroscopy analyzer in situation of 1.0~4.0 GPa, 1 073~1 573 K and 10-1~107 Hz frequency ranges. The experimental results indicate that the complex impedance spectra of iherzolite strongly depends on frequency, at the same time we explain it by virtue of electrical conduction: grain boundaries, grain interiors as well as between sample and electrode; the temperature is an important parameter deciding the electrical conductivity. As temperature increases, the electrical conductivity augments. The relationships between lg σ and 1/T accord with Arrenhius relation formula; this is the first time that the pressure as a controlling ingredient is well brought forward: As the pressure increases, the block rate advances; at the same time the electrical conductivity decreases.
