Extended Data Fig. 1: Oxygen diffusion coefficients in periclase.
From: Periclase deforms more slowly than bridgmanite under mantle conditions
The black dotted line corresponds to the fit of Ita and Cohen14 diffusion law at 0 GPa on the experimental data of Yoo et al.40. Comparison with results of Yang and Flynn15 results is provided. The other lines (blue, green, red and magenta) correspond to this new set at 30, 60, 90 and 120 GPa respectively. The square symbols correspond to the diffusion coefficients along the geotherm deduced from this data. Comparison with data from Ita and Cohen14 used in the main text (filled circles symbols) is provided
