Outline of Final Research Achievements

Deep-sea ferromanganese crusts and nodules are potential future metal resources for Co, Ni, REE, Pt or other elements, but the chemical and physical properties are yet fully understood on nano- to global scales. We, jointly with national and international institute, conducted hi-tech analyses and on-site exploration for understanding the geoscientific parameters controlling their compositional and physical properties and their variability. Our 3-year research program provided important geochemical and mineralogical and chronological data of ultra-slow growth, modern precipitation, water-depth dependency of some redox-sensitive soluble metal elements, which are of practical use in exploring the ore deposits or in archiving the pleoceanographic environments.

Academic Significance and Societal Importance of the Research Achievements

研究成果は、新生代海洋の古海洋学的環境変動と海水研における重金属元素の地球化学的挙動との関連解明に活用することができ、例えば、海洋大循環の地質時代における変動や惑星の軌道要素、短期間の地質イベントなどとの対応、さらに海洋環境復元の基礎資料としての意義が確認された。今後は海洋コアとの対比を含めた研究展開が期待できる。同時に現在我が国などが、国家事業として進めている、海底レアメタル資源の探査/開発に当たり、我々のデータは、鉱区選定や資源量評価に当たっての理論的根拠を与えることができる。
