The MgSiO3 system at high pressure: Thermodynamic properties of perovskite, postperovskite, and melt from global inversion of shock and static compression data (2009, methodology): “perovskite to postperovskite phase transition in (Mg,Fe)SiO3 [Murakami et al., 2004; Oganov and Ono, 2004; Hirose, 2006 ], which was predicted by the seismological study of Sidorin et al. [1999].”
GyPSuM: A joint tomographic model of mantle density and seismic wave speeds (2010, background): “(pPv) creating a partial de-correlation of P and S-wave heterogeneity [Murakami et al. 2004; Oganov and Ono 2004; Iitaka et al. 2004; Tsuchiya et al. 2004; Wookey et al. 2005; Hirose 2006; Hernlund and Houser 2008; Hutko et al. 2008].”
Core–mantle boundary heat flow (2008, background): “This situation appears to have changed with the discovery of a phase transition of (Mg,Fe)SiO 3 perovskite (Pv) — the primary mineral in the lower mantle — to a dense polymorph called post-perovskite (pPv) at pressure and temperature ( P – T ) conditions within the lowermost mantl”
Phase relations and equation of state of a natural MORB: Implications for the density profile of subducted oceanic crust in the Earth's lower mantle (2010, methodology): “[2005] and Hirose et al. [2005] using similar starting compositions are also plotted for comparison. Below 60 GPa, our result is similar to the result of Hirose et al. [2005]. The densities determined by Ono et al. [2005] are lower than ours, and those determined by Hirose et al. [2005] are higher a”
On the statistical distribution of seismic velocities in Earth's deep mantle (2008, methodology): “Estimates of a velocity jump up to several percent in VS and almost no change in VP for the Pv–pPv transition appear to be compatible with the presence of seismically observed discontinuities near the top of the D′′ layer (Iitaka et al., 2004; Tsuchiya et al., 2004; Wookey et al., 2005; Hirose, 2006”
Temperatures, Heat, and Energy in the Mantle of the Earth (2007, methodology): “According to the latest experiments (Hirose et al., 2006; Hirose, 2006), this phase change has a Clapeyron slope of 11.”
