Our research area expands to not only Japan also around the world, especially Asia and Africa. We aim to explore mineral and hydrocarbon resources there in collaboration with local university or research institute. Our recent research topics include (1) establishment of geo-resource database of ore deposits based on understanding of genesis and mineralization age of mineral deposits associated with island arc magmatism (e.g., epithermal gold and porphyry copper deposits), (2) monitoring and prediction of volcanic eruption by analyses of ejecta, (3) experimental study on hydrothermal geochemistry such as adsorption and precipitation behavior of materials dissolved in aqueous thermal solution and its application to recycling of rare and precious metals. Analytical techniques and instruments applied in laboratory include; X-ray diffractometer and scanning electron microscope for identification and observation of rock samples, electron probe microanalyzer 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 microthermometry, FTIR for determination of water contents in volcanic glass, atomic absorption, ICP-AES and ICP-MS for determination of dissolved components in aqueous solutions, fission track, K-Ar and Ar-Ar methods for age dating, X-ray photoelectron spectroscopy, X-ray absorption spectroscopy and nuclear magnetic resonance for determination of the chemical state or coordination structure.
