Figure 11
Simulations of MgSiO₃ and YAlO₃ in terms of η_A and η_B. (a) MgSiO₃ with regular octahedra up to p = 125 GPa; (b) comparison of YAlO₃ with regular and distorted octahedra up to p = 8 GPa; (c) Extrapolation of YAlO₃ with regular and distorted octahedra up to p = 52 GPa. Dashed lines indicate pressures for which structural data are quoted in Table 10
