Extended Data Table 1. Analyses of the Mg and Al concentrations in the metal and silicate phases of the experimental runs.
Experimental conditions (pressure in GPa, temperature in K, uncertainties in parentheses) and phase composition; all compositions are in molar fractions, and standard errors are 1-sigma. The values for log KD are plotted in Fig. 1 and Extended Data Fig. 2. Full chemical analyses of the samples can be found in an excel spreadsheet available online.
