Unit cell volumes of (Mg,Fe)SiO3 bridgmanite and ppv versus pressure. The unit cell volumes of the Fe-depleted bridgmanite at 102.5 GPa and the ppv phase at 119 GPa coexisting with the H-phase are compared with the equations of state for Fe-free MgSiO3 bridgmanite (Lundin et al. 2008) and (Mg0.91Fe0.09)SiO3 bridgmanite (Dorfman et al. 2013)
