Change Type: Update

Change Details: In the version of the Supplementary Material published alongside this article, there were errors in the Supplementary figures and text. In Figs. S1A, S1C, S1E, S1G and S1I, the Fe³⁺AlO₃, Fe²⁺SiO₃, AlAlO₃, MgAlO₂.₅ and Fe³⁺Fe³⁺O₃ components in bridgmanite were mistakenly calculated assuming a total of 40% instead of 100%. In the revised figures, the values of these components have been multiplied by a factor of 2.5. The y-axis labels on Figs. S1B, S1D, S1F, S1H and S1J were initially written as “Partition coefficient,” whereas they should read “Exchange coefficient.” According to the factor 2.5 increase in the values in Figs. S1A, S1C, S1E, S1G and S1I, the following text has been changed: In the second paragraph: K_{{\rm Fe}^{2+}-Mg}^{Bdm-Fper} remains essentially constant, despite \chi_{{\rm Fe}^{2+}O}^{Fper} decreasing from 14 to 5 mol.%.  However, K_{\Sigma Fe-Mg}^{Bdm-Fper} exhibits a marked increase from 0.7 to 3.1 as f_{O_2} rises, reflecting the presence of Fe3+ in Bdm but not in Fper. => K_{{\rm Fe}^{2+}-Mg}^{Bdm-Fper} remains essentially constant, despite \chi_{{\rm Fe}^{2+}O}^{Fper} decreasing from 18 to 6 mol.%.  However, K_{\Sigma Fe-Mg}^{Bdm-Fper} exhibits a marked increase from 0.4 to 2.3 as f_{O_2} rises, reflecting the presence of Fe3+ in Bdm but not in Fper. In the third paragraph: remains constant, but K_{\Sigma Fe-Mg}^{Bdm-Fper} decreases significantly, from 1.1 to 0.8, => increases from 0.3 to 0.4, but K_{\Sigma Fe-Mg}^{Bdm-Fper} decreases, from 0.7 to 0.6, In the fourth paragraph: K_{{\rm Fe}^{2+}-Mg}^{Bdm-Fper} decreases  with increasing P => K_{{\rm Fe}^{2+}-Mg}^{Bdm-Fper} increases with increasing P In the fifth paragraph: K_{\Sigma Fe-Mg}^{Bdm-Fper} shows an even more pronounced decrease => K_{\Sigma Fe-Mg}^{Bdm-Fper} shows complex increase, decrease and increase In the sixth paragraph: As Fe/Mg increases, Bdm Fe3+/ΣFe shows a slight decrease. => As Fe/Mg increases, Bdm Fe3+/ΣFe shows a decrease. In addition, the following typos have been corrected: In the first paragraph: Mg:Fe:Al:Si => Fe:Mg:Al:Si In the third paragraph: \chi_{{\rm Fe}^{2+}{\rm SiO}_3,Bdm} and \chi_{{\rm Fe}^{2+}O}^{Fper} show =>  \chi_{{\rm Fe}^{2+}{\rm SiO}_3}^{Bdm} shows In the seventh paragraph: Fe:Mg:(Al+Si) of 6.17:52.4:43.15 => Fe:Mg:(Al+Si) of 6.17:49.85:43.15 Figure captions: Fe3+Fe3+O3 (maron) => Fe3+Fe3+O3 (dark yellow) (A, B) as a function of temperature => (A, B) as a function of the difference of \log{f_{O_2}} from that of the IW buffer (C, D) as a function of the difference of \log{f_{O_2}} from that of the IW buffer => (C, D) as a function of temperature. Text and figures are now updated in the Supplementary Information.
