[S-RD39] [JJ] Resource geology

Thu. May 25, 2017 9:00 AM - 10:30 AM A07 (Tokyo Bay Makuhari Hall)

convener:Tsubasa Otake(Division of Sustainable Resources Engineering, Faculty of Engineering, Hokkaido University), Tatsuo Nozaki(Research and Development Center for Submarine Resources, Japan Agency for Marine-Earth Science and Technology), Kenzo Sanematsu(Mineral Resource Research Group, Institute for Geo-Resources and Environment, Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology), Ryohei Takahashi(Graduate School of International Resource Sciences, Akita University), Chairperson:Tsubasa Otake(Division of Sustainable Resources Engineering, Faculty of Engineering, Hokkaido University)

Ore deposits consisting of supracrustal concentrated valuable elements and minerals are results of the Earth's dynamics, including magmatism, hydrothermal activity, metamorphism, and weathering process. The formation of ore deposits is also closely associated with global environmental changes and biological evolution in the Earth's history. Therefore, involvement of various academic fields in Earth science, such as geology, petrology, geochemistry, mineralogy, and microbiology, is required to elucidate 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 environmental problems that may be caused by the development of mineral resources. This session covers topics that are related to supracrustal migration and concentration of elements by various aspects and methodologies, such as field investigation and observation, analytical development, laboratory experiment, and theoretical calculation.
