Outline of Final Research Achievements

Water in the Earth has been transported from the oceans into its deep interior, where it forms hydrous deep mantle minerals. Wadsleyite and ringwoodite have been considered as the two most important host minerals incorporating this type of water as hydroxyl groups. To constrain the capacity of water in their structures and also to understand the effect of such water on their physical properties, it is essential to quantitatively determine the sites and occupancies of hydrogen in their structures. We thus conducted neutron time-of-flight Laue single crystal diffraction studies of synthetic crystals of them. Single crystals, which have size and quality suitable for the method, were synthesized by a newly-developed slow-cooling method at the relevant high pressure and temperature conditions. The structures of two hydrous minerals have been successfully determined in very high resolution in space.
