Outline of Research at the Start

本研究は、海洋底の大部分を占める遠洋性粘土をキーマテリアルとして捉え、「化学層序プローブ」を用いて網羅的に解析することで、グローバル環境変動・物質循環のダイナミクスの全容を定量的に解明する研究である。また、有用元素の循環を定量的に議論することで、資源成因の支配プロセスの全体像を解明する。そして、環境変動や資源生成を統一的な枠組みで説明可能な,真に革新的なグローバル物質循環についての統合理論の創成を目指す。

Outline of Final Research Achievements

In this study, to analyze the origin of rare-earth element (REE)-rich mud, we comprehensively investigated deep-sea sediments from various ocean regions with multiple analytical techniques, including the application and extension of chemostratigraphy for pelagic clays, further refinement and application of dating methods, high-dimensional data analyses, and the combination of these techniques with chemostratigraphic probes and isotopic analyses. Furthermore, we constructed the world's first mathematical model of REE mass balance considering interactions between the ocean and sediments. Using this model, we conducted numerical simulations and quantitatively examined the conditions for the formation of REE-rich mud. As a result, we successfully demonstrated for the first time in the world that high-grade REE-rich mud was formed over a wide area of the Pacific Ocean during the early Cenozoic greenhouse period.

Academic Significance and Societal Importance of the Research Achievements

本研究では,「化学層序プローブ」を用いた遠洋性粘土からの情報抽出に世界で初めて成功した.そして,それらの解析結果を基に,世界初となるレアアース泥の生成に関する数理モデルを構築した.その結果,始新世前期の堆積層がレアアース泥探査の有望なターゲットであるという,画期的な資源探査指針が得られた.以上のように,本研究成果は学術的および社会的意義それぞれの観点から,極めて重要度の高いものといえる.
