| Outline of Final Research Achievements |
This research is an attempt to read the important record concerning the earth and planet activity that remains in and crystal structures and local structure of elements in solids. The experiments are performed in-situ, by using world’s top level equipment such as the synchrotron facilities. Information on the short to long range order structures is obtained by XAFS and the diffraction methods. Physical property, electronic state and atomic revel structure analyses are put into close contact to investigate details of the melt, glass and crystal materials under extreme conditions. Information on extreme conditions at meteorite impact is frozen in local in impact related glasses. The density of the low-T solid phase is smaller than that of high-T liquid in some P-T region. The existence in such pressure region is general in covalent bond materials. We have clarified the origin on unique valence states and coordination environments in the Earth’s mantle origin minerals.
