Extended Data Fig. 3: Creep laws in bridgmanite (Bdm) and periclase (Per).
From: Periclase deforms more slowly than bridgmanite under mantle conditions
In this figure we illustrate the influence of possible uncertainties on the diffusion coefficients in bridgmanite and periclase. For bridgmanite (Bdm) vacancy concentrations of 10−3 and 10−6 are considered. Creep in periclase is based on diffusion data of Ita and Cohen14 and Yoo et al.40. Whatever the set of data considered, bridgmanite always deform faster than periclase
