研究室紹介

Our research area extends not only to Japan, but also to the entire world, especially Asia and Africa. We aim to explore mineral and geothermal resources there in collaboration with local university or research institute. Our recent research topics include (1) establishing a geo-resource database of ore deposits based on understanding of the genesis and mineralization age of mineral deposits associated with island arc magmatism (e.g., epithermal gold and porphyry copper deposits), (2) monitoring and predicting silica scale precipitation in geothermal power plants, (3) understanding the geochemistry of critical metals in magmatic-hydrothermal systems and surface environments and its application to the recycling of critical and precious metals. Analytical techniques and instruments applied in the laboratory include; X-ray diffractometer and scanning electron microscope for identification and observation of rock samples, electron probe micro analyzer for determination of chemical composition in microscopic scale, X-ray fluorescence spectrometer for determination of whole-rock chemical composition, heating/freezing stage for fluid inclusion micro thermometry, AAS, ICP-AES and ICP-MS for determination of dissolved components in aqueous solutions, LA-ICP-MS for determination of trace elements in solid and U-Pb age dating, X-ray photoelectron spectroscopy, X-ray absorption spectroscopy and nuclear magnetic resonance for determination of the chemical state or coordination structure.
