Mon. May 26, 2025 5:15 PM - 7:15 PM Poster Hall (Exhibition Hall 7&8, Makuhari Messe)

convener:Mihoko Hoshino(National Institute of Advanced Industrial Science and Technology), Yoko Ohtomo(Faculty of Engineering, Hokkaido University), Ryohei Takahashi(Graduate School of International Resource Sciences, Akita University), Tatsuo Nozaki(Department of Resources and Environmental Engineering, Faculty of Science and Engineering, Waseda University)

Ore deposits containing valuable elements and minerals at high concentrations in supracrustal rocks are formed by the Earth's dynamics including magmatism, hydrothermal activity, metamorphism, and weathering. The formation of ore deposits is also closely associated with global environmental changes and biological evolution in the Earth's history. Involvement of difference academic fields in earth sciences including geology, petrology, geochemistry, mineralogy, and microbiology is required to understand the genesis of ore deposits. The field of resource geology is essential not only for efficient exploration and development of ore deposits but also for better understanding and assessment of hazardous elements that may be caused by the resource development. This session widely covers various topics of field investigation and observation, laboratory experiments, theoretical calculation, development of analytical methods and others related to the supracrustal migration and concentration of elements. We also welcome research related to new energy resources (e.g., hydrogen, geothermal), efficient extraction of metal resources, and net zero carbon emission, and so on, in either scientific or engineering perspective.
