| Outline of Final Research Achievements |
The aim of this study is to understand the chemistry of crystallizing magma ocean based on high-pressure experiments using diamond anvil cell. Aiming at solving technical problems which may be the cause of inconsistency on melting phase relations reported by various groups, we (1) have introduced X-ray laminography to construct high-pressure and high-temperature in-situ X-ray chemical imaging measurement system at BL47XU, SPring-8, (2) have developed an internal resistance-heating technique using boron-doped diamond heater. In addition, we have developed large-strain, torsional deformation apparatus at high pressures up to 135 GPa with a help of hard nano-polycrystalline diamond anvils.
