Introduction of Research
Clay minerals are major mineral components in the environment of the earth's surface. My students and I study structure, formation mechanisms and physical/chemical properties of clay minerals. We also investigate geologic phenomena such as earthquake and landslide, focusing especially on the role of clay minerals on these processes.
