Figure 4
(a) Viscosity of bridgmanite along the geotherm for stresses of 10 (red lines) and 1 (blue lines) MPa and vacancy concentrations Xv of 10−2 (solid lines) and 10−6 (dashed lines). The obtained absolute values and variability of viscosity are compared with the data of Forte and Mitrovica13, Mitrovica & Forte14, Steinberger & Calderwood68 and (b) Rudolph et al.17 (R15). The scale on the y axis is the same for the (a) and (b) figures.
