SEM elemental maps (Fe, Mg, Si, O and S) of hydrous samples, (a) without S recovered at 10.7 GPa and 1116 K (#A534) of the area surrounded by a red square in the upper left electron image and (b) with S recovered at 6.5 GPa and 1000 K (#A433). Ol olivine (Mg, Fe)2SiO4; Px pyroxene (Mg, Fe)SiO3; En enstatite MgSiO3. Olivine containing rich Fe located close to Fe whereas pyroxene was poor in Fe almost like enstatite and located far from the iron.
