Pressure-induced structural change in MgSiO3 glass at pressures near the Earth’s core-mantle boundary [Earth, Atmospheric, and Planetary Sciences]

Knowledge of the structure and properties of silicate magma under extreme pressure plays an important role in understanding the nature and evolution of Earth’s deep interior. Here we report the structure of MgSiO3 glass, considered an analog of silicate melts, up to 111 GPa. The first (r1) and second (r2)...
