| Outline of Final Research Achievements |
We carried out the experimental research on the structural changes of the deep mantle materials by using Brillouin scattering and Raman scattering measurement system in a laser diamond anvil cell high-pressure and high-temperature apparatus, which can achieve to reproduce the relevant condition to the deep Earth.
By establishing the combined spectroscopic measurement system under high pressure and high temperature condition, we succeeded to obtain insight into the structural changes not only for the solid phases but also liquid phases under high-pressure and high-temperature condition. This result will give us the important information to constraint on the internal evolution of the early Earth.
