    Abstract
  • We performed in situ electrical conductivity measurements on pure and iron FeS-bearing olivine in a multi–anvil apparatus using the impedance spectroscopy technique under the condition of 1–3 GPa and 723–1273 K. The experimental results indicated that the electrical conductivities of 15% (mass fraction) FeS–bearing olivine, in the range of 0.1–10 S/m, are 2 to 3 orders of magnitude higher than that of pure olivine in the experimental temperature range. The electrical conductivities of pure and 15% FeS-bearing olivine increase with increasing temperature. The dependence of the electrical conductivity of pure olivine on temperature is much stronger. The effect of pressure on the electrical conductivity of pure and iron FeS-bearing olivine is different. With the rise of pressure, the electrical conductivity of pure olivine slightly decreases, whereas the electrical conductivity of the 15% FeS-bearing olivine increases significantly. Based on the experimental results including the Arrhenius parameters, it is proposed that the 15% FeS can form an interconnected network in olivine, which dominates the conduction process of olivine.
