摘要

Electrical conductivity of two-pyroxene granulite, collected from north margin of North China craton, was measured at 1.0~2.0 GPa and 523~1 173 K by using three different methods at the same time. The experiments were carried out in a measurement system of electrical conductivity, which consisted of an YJ-3000t multi-anvil apparatus, a Solartron IS-1260 Impedance/Gain-Phase analyzer, an Agilent 34401A Multimeter, and a computer. The experimental results indicate that within the range of experimental temperature and pressure, the electrical conductivity of two-pyroxene granulite changes from 2.66×10^-5 S·m^-1 to 0. 056 S ·m^-1, and hardly has a dependence on the given pressure. With increasing temperature, the electrical conductivity increases.
