Fig. 4. — Pressure condition of the ultrahigh-pressure structural change in MgSiO₃ glass obtained in this study, compared with bridgmanite–postperovskite transition in crystalline MgSiO₃ [open black triangle (28)]; open black circle and diamond: generalized gradient approximation (GGA) and local density approximation (LDA) calculation, respectively, by ref. 31; solid black line (32) and a structural change in MgSiO₃ melt predicted by MD simulation (27) (solid black square). Solid and dashed green line represents melting temperature of pyrolite (4) and peridotite (3), respectively.
