The unit-cell volume of ferropericlase before (stars) and after (circles) heating and subsequent decompression to 1 bar for heating runs Mg50-2 (black) and Mg90-1 (yellow). Also shown are compositional curves for the pressure–volume relationship of (Mg,Fe)O with various Fe contents: 1FeO from Fischer et al. (2011), 2(Mg,Fe)O from Fei et al. (2007), and 3MgO from Speziale et al. (2001).
