We report the first systematic experimental study of melting behavior in the MgO‐FeO system up to 3600 K and 7 GPa, indicating the ideal solution between solid and liquid (Mg,Fe)O in the MgO‐rich portion. The zero pressure melting slope of MgO is ∼221 K/GPa derived from our resistance heating measurements, which is several times higher than the value from the previous measurements in a CO<jats:sub>2</jats:sub>‐laser heated diamond anvil cell, but consistent with the theoretically predicted melting curves. Our results combined with the previous first‐principles simulations suggest that the melting temperature of MgO‐rich (Mg,Fe)O is significantly higher than the geotherm through the lower mantle and this would place an upper bound on the solidus of the lower mantle.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699994948209152","@type":"Researcher","foaf:name":[{"@value":"Li Zhang"}],"jpcoar:affiliationName":[{"@value":"Geophysical Laboratory Carnegie Institution of Washington  Washington D.
