Abstract
Water is the most abundant volatile component on the Earth's surface, and it is important to clarify the water distribution in the Earth's interior because water influences the physical properties and melting temperature of minerals. Here the author reviews our recent works about the H2O partitioning among high-pressure polymorphs of olivine. Based on the partitioning results combining with the seismological constraint, the author discusses the amount of water distribution in the Earth's interior.
