Research Abstract

Field works in Kerala, southern India and Adirondack Mountains, NY were done. Petrographic observations of samples from these localities were done. It has been confirmed that CO_2 fluid inclusions in garnet and zircon were common in these lower-crust rocks. A numerical model of the CO_2 cycle connecting the solid Earth and the surface environment was constructed. It has been demonstrated that an expected decarbonation event in the Proterozoic had extensive effect to the Earth's surface temperature. A new method to estimate a thermal structure of the subduction zone was developed. These results were presented in 6 talks and published as 13 papers in academic journals.
