| Outline of Final Research Achievements |
Heat transport inside the Earth is essential property which controls the rate of core heat loss and the long-term thermal evolution of the Earth, but it has been poorly constrained because of high pressure and high temperature conditions inside the Earth.
In order to experimentally observe thermophysical properties of the Earth’s core and mantle materials, we have developed thermal conductivity measurement apparatus based on the pulsed light heating thermoreflectance method, which was utilized diamond anvil cell technique. We observed pressure, temperature and composition dependence of thermal conductivity for core and mantle materials, such as iron, ferropericlase, bridgmanite, MgO-FeO solid solutions and etc. These facts can reveal more exact estimation on heat flow across core-mantle boundary.
