英文摘要
The Earth consists of 70% of MgO-rich peridotite (mantle) and 30% of Fe-Ni-rich metallic core. Basalt which is the main component of the Earth's crust is formed by partial melting of the mantle peridotite. Role of magma (melting phenomenon) has played very large role in the Earth's interior evolution (chemical differentiation). We have carried out high-pressure experiments and succeeded for the first time to reproduce experimentally the pressure dependence of the partition coefficient of trace elements between crystals and magma (PC-IR diagram).We proposed a theory that explains the pressure dependence.
