Melt has much higher element diffusivity and is much more mobile. Melts should play vital roles in geochemical processes in the Earth's interior. Melt properties are, however, difficult to investigate by high P-T experiments due to the following reasons.
In order to overcome these problems, we have developed the following technologies.
We are investigating melting relations, element partitioning and melt (quenched glass) structures by using these technologies.
