• Theoretical and experimental evidence for a post-perovskite phase of MgSiO3 in Earth's D" layer.

  The Earth's lower mantle is believed to be composed mainly of (Mg,Fe)SiO3 perovskite, with lesser amounts of (Mg,Fe)O and CaSiO3 (ref. 1). But it has …

• Anisotropy of Earth's D'' layer and stacking faults in the MgSiO3 post-perovskite phase.

  The post-perovskite phase of (Mg,Fe)SiO3 is believed to be the main mineral phase of the Earth's lowermost mantle (the D'' layer). Its properties expl…
