| Research Abstract |
Hydrous components in mantle-forming material can induce considerable change in deformation behavior, melting relationship and wave propagation of earthquake. In this project, we have investigated pressure-induced structural responses surrounding hydrogen atoms. In paticular, hydrous magnesium silicate and some hydrogen carbonate were investigated by vibrational spectroscopy and neutron diffraction at high pressure. Please refer our original papers for the details.
