| Research Abstract |
Newly developed in-situ high-pressure and high-temperature sound velocity measurement system revealed the sound wave propagating velocities of various lower mantle phases including MgO, H2O, (Mg,Fe)O, Mg-perovskite, SiO_2 glass and MgSiO_3 glass which lead to put the tighter constraints on the mineralogical model of the lower mantle.
