本セッションでは，海底鉱物資源 (海底熱水鉱床，マンガン団塊，マンガンクラスト，レアアース泥) およびその陸上アナログ (火山性塊状硫化物鉱床，層状マンガン鉱床，層状鉄マンガン鉱床 (アンバー)) を主な対象とします．地質学・地球化学・地球物理学・微生物学的研究，鉱床の成因や元素の濃集機構の解明，これらを理解するための室内実験や手法開発，鉱床モデルの精緻化，環境影響評価，坑廃水処理や環境対策，最近の野外調査・研究航海の紹介など，海底鉱物資源とその陸上アナログに関する発表を広く歓迎します．JpGU-AGU2026に合わせて開催する時限セッションですので (東京で開催されるGoldschmidt 2028への継続を計画中)，各学会や研究分野の垣根を超えた交流や意見交換の場に繋がることを期待します．

The main targets of this session are seafloor mineral resources such as seafloor hydrothermal deposits, ferromanganese nodules, ferromanganese crusts and rare-earth element-rich muds, as well as their natural analogues on land such as volcanogenic massive sulfide (VMS) deposits, and stratiform and stratabound manganese and ferromanganese (umber) deposits. Any researches focusing on the geology, geochemistry, geophysics, microbiology, metallogenesis and enrichment mechanisms of targeted elements, laboratory experiments and method development, modeling of ore forming processes, environmental impact assessments, mine drainage treatment and environmental remediation, introductions of recent field investigation and research cruises are highly welcome. Since this session is restricted to JpGU-AGU 2026 (possibly continued to Goldschmidt 2028 in Tokyo), we expect this session to facilitate vigorous multidisciplinary discussion and academic exchange beyond the research fields, which are impossible at only one academic society.
