The method is described which utilizes slow (10-100 mHz) AC current to determine the electrical conductivity of ferromagnesian minerals at pressures up to 23 GPa and temperatures of 300-2000 K in the 6-8 type multi-anvil high-pressure apparatus. The oxidation state of the sample is controlled just below IW buffer. The range of electrical conductivity which can be measured using the present method is 100Ω-5MΩ. An example of measurement was conducted for Mg<SUB>0. 93</SUB>Fe<SUB>0. 07</SUB>SiO<SUB>3</SUB> ilmenite.
