Outline of Annual Research Achievements

海洋中のOs同位体比を検討するための試料として最適な層状チャート層の層序学的検討を引き続き行った。期間中に新たに発見した秩父帯中の三畳系-ジュラ系境界層の詳細な層序学的検討を実施すると共に，層状チャート中におけるジュラ系ー白亜系(J-K)境界層の探索を行い，本邦においてJ-K境界を含有する可能性のある層序断面を発見した。
また，岐阜県郡上八幡地域に露出する岩石を用い，約2.6億年前のGuadarupian/Lopingian境界絶滅事変時の深海は同時代他地域の浅海に比べると，それほど還元的ではなく，suboxic程度であったことを明らかにした。この時期の大規模火勢活動は深海全域に影響するほどではなく，そのために深海の生物はそれほど絶滅しなかったものと考えられる。
さらに，美濃帯犬山地域に分布する後期三畳紀カーニアンの層状チャートを対象に，コノドント化石を用いた詳しい化石年代の決定および，Os同位体測定を行なった。研究の結果，カーニアン前期の約500万年間にわたり著しいOs同位体比の低下が認められた。これはカーニアン多雨イベントを導いた，Wrangellia洪水玄武岩の噴出を記録している可能性がある。
また，マンガンクラストで見られていた1200万年前のOs同位体比の負の異常を堆積物コア試料のOs同位体比の負異常として発見した。この負異常はコロンビアリバー洪水玄武岩によってもたらされた可能性が高い。
地質境界においては，ペルム紀-三畳紀境界，白亜紀-古第三紀境界など大量絶滅が生じた地質年代境界に焦点を当て，当時の記録を残している堆積岩試料の白金族元素濃度プロファイルを作成した。
成果公表として上記の成果のいくつかを論文として公表した。さらに，Island Arc，Paleontol. Res.誌にInterRad特集号を組み，複数の論文を公表した。
