Figure 5: Stereo projections of elastic wave velocities for Pv- and pPv-MgSiO3.

The crystallographic directions, a, b, and, c, are identical in each plot as shown in (a). The unit of scale bars is m s−1, although a factor of 104 should be multiplied for VP. (a–c) VP, average of two VS values, and difference between two VS values, respectively, for Pv-MgSiO3 under ambient conditions. (d–f) and (g–i) Same as a, b, and c but for Pv-MgSiO3 and pPv-MgSiO3 at 125 GPa and 2,500 K10, respectively.
