I am interested in (a) Evolution of the oceanic mantle: Main fields for this scientific topic are oceanic islands and the ocean floor, from which mantle peridotites can be collected. With analytical application of nano- to micro-meter-scale techniques to tiny minerals therein, host minerals of platinum-group elements can be investigated. In addition, with measurements of bulk highly siderophile elements (HSE), I would like to reveal evolutionary process of the Earth. (b) Hydrothermal activity beneath the ocean floor: Main fields for this scientific topic are ophiolites and the ocean floor, from which hydrothermally altered rocks can be collected. Through intensive investigations into µm-scale fluid inclusions therein, chemical characteristics of hydrothermal fluids can be investigated. I would like to reveal mechanism of the elemental mobility via hydrothermal activity.
