(a)–(c) XES spectra of Mg0.67Fe0.33O ferropericlase at high pressure and high temperature. The lower curves in each plot are difference curves with respect to the spectrum at the lowest pressure shown, ×3 in (b) for better visibility. Spectra are area-normalized and shifted to a common center of mass. (a) Comparison of ferropericlase spectra with those from Lin et al. (2005) at ambient and high pressure at ambient temperature. (b) Pressure sequence from ambient pressure to 69 GPa. (c) Temperature sequence at 78 GPa with differences with respect to ambient pressure. See Fig. 10 for evaluation. |
