Experimentally determined \({\mathrm{K}}_{\mathrm{D},\mathrm{Fe}^*-\mathrm{Mg}}^{\mathrm{ol}/\mathrm{liq}}\) (K_D*) for RKD experiments run at ƒO₂ ≤ IW + 0.5 plotted vs. A Temperature, B FeO* wt% in glass, C Fo% = 100(Mg/[Mg + Fe], molar) in olivine. Symbols as in Fig. 1. The olivine compositions used to calculate \({\mathrm{K}}_{\mathrm{D},\mathrm{Fe}^*-\mathrm{Mg}}^{\mathrm{ol}/\mathrm{liq}}\) all come from analyses of olivine rims. Error bars are 1σ and errors for the quantities plotted on the x-axis are smaller than the symbol sizes
