    We describe variations in trace element compositions that occurred on the deep seafloor of palaeosuperocean Panthalassa during the end-Permian mass extinction based on samples of sedimentary rock from one of the most continuous Permian-Triassic boundary sections of the pelagic deep sea exposed in north-eastern Japan. Our measurements revealed low manganese (Mn) enrichment factor (normalised by the composition of the average upper continental crust) and high cerium anomaly values throughout the section, suggesting that a reducing condition already existed in the depositional environment in the Changhsingian (Late Permian). Other redox-sensitive trace-element (vanadium [V], chromium [Cr], molybdenum [Mo] and uranium [U]) enrichment factors provide a detailed redox history ranging from the upper Permian to the end of the Permian. A single V increase (representing the first reduction state of a two-step V reduction process) detected in uppermost Changhsingian chert beds suggests development into a mildly reducing deep-sea condition less than 1 million years before the end-Permian mass extinction. Subsequently, a more reducing condition, inferred from increases in Cr, V, and Mo, developed in overlying Changhsingian grey siliceous claystone beds. The most reducing sulphidic condition is recognised by the highest peaks of Mo and V (second reduction state) in the uppermost siliceous claystone and overlying lowermost black claystone beds, in accordance with the end-Permian mass extinction event. This significant increase in Mo in the upper Changhsingian led to a high Mo/U ratio, much larger than that of modern sulphidic ocean regions. This trend suggests that sulphidic water conditions developed both at the sediment-water interface and in the water column. Above the endPermian mass extinction horizon, Mo, V and Cr decrease significantly. On this trend, we provide an interpretation of drawdown of these elements in seawater after the massive element precipitation event during the end-Permian maximum development of the reducing water column. A decrease in the Mo/U ratio despite enrichment of Mo and U also supports that of Mo. Calculations of the total amounts of these elements precipitated compared with the global seawater inventory suggest that when more than 6-10% of the global ocean became euxinic as much as the study section, most of the dissolved elements would precipitate into sediments, resulting in a global element-depleted seawater condition. Mo, V, and Cr act as bioessential elements for both primary producers and animals. The continuing reducing water column and the lack of bioessential elements could have had a considerable effect on primary producer turnover and marine life metabolism not only in the pelagic environment, but also in surrounding marine environments.

    本研究では続成作用が堆積物中の重元素安定同位体比に与える影響について熱水反応実験と堆積物コア試料の分析を組み合わせて解明することを目的とし、①安定同位体比分離法および分析条件の確立、②天然試料採取と同一層準決定、③熱水反応実験、④天然試料および実験試料の安定同位体比および配位環境分析という4つの研究ステップを4年間で行う計画をしている。
    2020年度は①の元素分離法および分析条件の確立に加えて、②の国際深海科学掘削計画(IODP)第346航海で採取された新第三紀の日本海堆積物コアの分析を開始した。①について、Fe安定同位体比測定では、これまで行われていたCuを添加してピークジャンプ測定を行い、Cu同位体比からFe同位体比を補正する手法よりも、Niを添加してピークジャンプをせずにNi同位体比でFe同位体比を補正することで、分析精度の大幅な向上を実現した。②については、当初予定していた倍の試料を入手したことから、試料処理に要する時間が大幅に増えたことも影響し、同一層準決定までは達成できていない。しかし、蛍光X線分析による主成分元素濃度測定およびICP-MS分析による微量元素濃度測定は合計221試料で完了している。③については、引き続きブランク実験を行い基礎データの取得を行った。

    This research project aims to reveal the coincidence of large volcanic activities and possible marine environmental responses such as the changes in primary producers and oxygen-poor oceanic condition during the severest mass extinction event in the Earth history (about 250 million years ago). To this end, we conducted fieldworks in the localities of deep-sea sedimentary which recorded the extinction event and used the collected samples for geochemical analysis (organic molecules, osmium isotopes, mercury concentrations, redox-sensitive elements). As our results, the trends that can be interpreted as the volcanic activity and enhanced weathering of volcanic rocks, which is indicated by the shift to low osmium isotope ratio and the peak of mercury concentration in the deep ocean stratigraphy, was obtained. At the similar time as this trend, ocean oxygen depletion occurs, and the increase in bacteriochlorophyll biomass slightly delay.
