Earth's Evolution and Environment

The main research subjects of this division are to elucidate the history and the law of changes and evolution of the Earth, and to analyze the dynamic properties of the Earth. Our current interests concern the structural and evolutional process of the Earth, crustal movements, the petrologic and rectonic structures of the island arc mobile belt, the crust-mantle interactions, the environmental changes of the Earth, and the physical and dynamic properties of the deepearth materials.

Staffs and Research Fields
