From: Hydrogen self-diffusion in single crystal olivine and electrical conductivity of the Earth’s mantle
Olivine electrical conductivity as a function of inverse temperature (in Kelvin) and H2O content. Calculations are shown for dry olivine36 as well as hydrous (this study), with 10, 80 and 250 ppm wt H2O. Yellow bands display electrical conductivity anomalies measured in the asthenosphere16,17,18, 48 (horizontal) and adiabatic temperatures calculated at such depths (~1350–1450 °C49, vertical). Temperatures in degrees °C are also shown at the top of the diagram.
