From: Molecular hydrogen in minerals as a clue to interpret ∂D variations in the mantle

Fig. 5

Diffusivity of hydrogen in silica glass43,44, effective diffusivity in olivine41, diffusivity in diopside as a function of crystallographic orientation42, and the effect of H2 partial pressure on diffusivity in glass46. The grey field corresponds to the temperature range of the lithospheric mantle (dashed lines correspond to low temperature extrapolation of experimental data).
