Research Abstract

We have clarified the phase and melting relations of the iron-light element systems to the earth's core conditions, the reactions of metallic iron and silicates at the core-mantle boundary, and the physical properties of metallic melts at high pressure. Using these data, we discussed the mechanism of the core formation and the nature and properties of the Earth's core.
