Electrical conductivities for olivine at 10 GPa, wadsleyite at 15 GPa and ringwoodite at 20 GPa, all with San Carlos (Mg_{0. 9}Fe_{0. 1}) ₂SiO₄ olivine starting composition were determined by complex impedance spectroscopy in a multianvil apparatus. Results for olivine are in good agreement with previous studies, both at elevated pressure and ambient pressure, suggesting that its conductivity is only weakly dependent on pressure. Conductivities for wadsleyite and ringwoodite are significantly higher than olivine (about 2 orders of magnitude), but with slightly lower activation energies. These differences can be attributed to the likely presence of ferric iron in the wadsleyite and ringwoodite.
