Extended Data Fig. 2: Pressure dependence of ionic diffusion.
From: Periclase deforms more slowly than bridgmanite under mantle conditions

The lines represent oxygen diffusion coefficients in periclase (Per). We compare the data of Ita and Cohen14 (solid lines) to those obtained from the pressure dependence of Ita and Cohen14 but anchored on data from Yoo et al.40 (dotted lines). The symbols correspond to magnesium diffusion in bridgmanite (Bdm) considering a range of vacancy concentrations from 10−3 to 10−6
