In Text S1, we introduce the major element compositions of the minerals in the run products, which is reported in Table S1 and shown in Figure S3. Figure S1 exhibits the representative EDS analysis of the quenched liquids.

Figure S2 demonstrates the accuracy of the EDS analysis; Figure S4 reports the Kd_(Fe-Mg)^(Ol/liquid) values, confirming the attainment of equilibrium during experiments.
