The dynamics and structure of the Earth's interior are associated with geologic processes observed on the surface. In addition, knowledge of the Earth’s interior is one of the keys to understanding the formation and evolution of the Earth and planets. We study the physical properties of mantle minerals at high pressure and high temperature in order to better understand the structures and dynamics of the Earth and other planetary interiors. |
