[B-BG02] Geo-Bio Interactions and its Applications

Mon. May 26, 2025 10:45 AM - 12:15 PM 301A (International Conference Hall, Makuhari Messe)

convener:Yohey Suzuki(Graduate School of Science, The University of Tokyo), Fumito Shiraishi(Earth and Planetary Systems Science Program, Graduate School of Advanced Science and Engineering, Hiroshima University), Keisuke Fukushi(Institute of Nature & Environmental Technology, Kanazawa University), Arisa Nishihara(RIKEN BioResource Research Center), Chairperson:Fumito Shiraishi(Earth and Planetary Systems Science Program, Graduate School of Advanced Science and Engineering, Hiroshima University), Arisa Nishihara(RIKEN BioResource Research Center)

Advances in research on the deep biosphere have revealed microbial ecosystems comparable to those at near-surface settings. The exploration targeting extant life and the traces of the past life (biosignatures) in rocks has expanded from Earth to the Martian sphere, while exploration and life-detection technologies are being developed. Regarding the interaction between atmosphere-water-rock/mineral-life, research has been conducted from various perspectives such as processes at the atomic and molecular levels, phenomena on the regional fluid flow scale, the action of creating rocks, and their responses in environmental changes. These studies are also important for solving problems such as energy and mineral resources, the global environment, and disasters. This session invites a wide range of basic and applied researches based on microbiology, mineralogy/petrology, geochemistry and analytical chemistry.
