Profile

- Methane hydrates are crystalline compounds composed of water and methane that form at high pressure and low temperature, ubiquitously found along the continental margins. Because of their pressure/temperature-sensitive nature, they have been formed or dissociated in response to the environmental changes during the earth's history. Our research aims to understand the linkage between methane hydrates and past-present-future environmental changes in terms of geochemical and sedimentological techniques.
- Natural iodine system has a long-lived radioisotope (129I; half-life of 15.7 Myr). The amount of 129I in geological fluids has been useful to determine the age of iodine-rich host sediments, providing a relative-age model for the fluid domain. We apply recently developed 129I geochronology for material transport and/or accumulation via fluid in the shallow geosphere.
