Electrical Conductivity of Olivine, Wadsleyite, and

One reason for uncertainties in the electrical conductivity of the mantle is the lack of laboratory measurements on transition-zone minerals. In the depth range 410 to 660 km, the most abundant upper-mantle mineral, Mg 1.8 Fe 0.2 SiO 4 olivine, transforms to the high-pressure polymorphs wadsleyite (∼410 km depth) and ringwoodite (∼520 km) …
