| Research Abstract |
From high pressure experiments, it has been reported that high pressure phases of olivine, which are main mineral component of mantle transition zone (from 410 to 660 km depth), can retain plenty of hydrogen in their crystal structures. Therefore, there is a possibility that significant amount of water is transported and stored in these phases in the mantle transition zone by mantle convection. In order to investigate and clarify the structure and bonding state of hydrogen in the high pressure phases of olivine, we conducted first principles electronic structure calculation and calculated vibrational properties of these phases using high performance computers.
