Outline of Annual Research Achievements

平成29年度は，主にペルム紀から三畳紀を経てジュラ紀に至る時代の海洋環境の変動に関して，地質学的イベントがおきた時期と平常期の双方に関して多くの知見が得られた。
イタリアシチリア島の遠洋性石灰岩を対象に，採取した試料についてはストロンチウム同位体分析を行い，後期三畳紀のノーリアン中期ー後期に，ストロンチウム同位体比が急激に上昇したことを明らかにした。一方，美濃帯層状チャートの中部ー上部ノーリアンにも，オスミウム同位体比の急激な上昇が記録されていることが明らかになった。そして同時代に起こったこれら同位体比の上昇は，パレオテチス海の収束に伴う造山運動によって引き起こされたとする新しい説を提唱した。
時代をさらに戻り，三畳紀末期の堆積物の研究も進展した。これまで陸域のデータに基づくと，三畳紀末期に炭素循環変動が起きた事が明らかになっていたが，地域によってその回数が異なり，また大規模火成活動Central Atlantic Magmatic Province (CAMP)との前後関係も自明ではなかった。そこで，より全球的な情報を残しているであろう犬山地域の深海堆積物を用い，有機炭素同位体比を測定した結果，3度の炭素循環変動が最初のCAMP火成活動よりも後に起こっていたことが明らかになった。また，炭素循環変動の期間から判断するに，これら炭素同位体比変動を隕石衝突等宇宙からの影響によって説明するのは難しい。これにより，これら炭素循環変動の根本原因はCAMPと関連しており，またその影響は3度に渡っていたことが初めてデータとして示された(Fujisaki et al., under review)。さらに，沖縄県伊江島から産するペルム紀から白亜紀の放散虫の産出について論文として公表した。
さらに時代を経て古第三紀に関しては，チベットの珪質岩セクションにおいて古第三紀放散虫の検討を行い，Lychnocanium属などの３新種を含む放散虫群集について記載論文として公表した。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

チベットの珪質岩セクションにおいて古第三紀放散虫の検討を行い，Lychnocanium属などの３新種を含む放散虫群集を記載した。日本の中古生代遠洋性堆積物の放散虫層序の検討を継続している。イタリアのセクションにおける下部白亜系の放散虫生層序の検討を開始した。
日本の中古生代遠洋性堆積物の放散虫層序の検討を継続している。イタリアのセクションにおける下部白亜系の放散虫生層序の検討を継続している。
ODP（海洋掘削プロジェクト）で採取された太平洋の古第三紀の堆積物を高知コア研のコアデポジトリにて採取し，ほぼすべての試料に関してオスミウム同位体比分析が完了した。
これらの試料の分析は最終年度に完了し，得られた結果を論文にまとめ，投稿できる見通しがたった。
以上から，おおむね順調に進展している。

Strategy for Future Research Activity

最終年度は，これまでに採取した試料の同位体分析を効率よく進め，環境変動とのリンクを十分に意識しながら，取得したデータをまとめて論文を投稿する。新生代の試料は，ODPによるコアをすでにサンプリングし，8割方の分析が完了したので論文としてまとめる。
重点を置く時代として，三畳紀-ジュラ紀-白亜紀の長期に渡る変動を対象とする。日本で新たに発見した秩父帯のTJB境界層及び美濃帯のTJBからToarcian Anoxic Eventまでの下部ジュラ系の追加調査研究と，これまでEU及び日本におけるT-J境界から下部ジュラ系にかけての分析値をまとめる。必要に応じて補足分析を実施し，国際学会での成果の公表と論文化を進める。また，珪質堆積物の起源である珪質殻骨格を持つプランクトンの殻形成時における地球化学的分布様式を試験的に検討する。さらに，美濃帯の中部三畳系（ラディニアン）から上部三畳系（ノーリアン）層状チャートを対象に，高精度の微化石層序および地球化学的分析を行い，この火山活動の詳しい活動期間や規模について明らかにする。
ジュラ紀・白亜紀境界（JKB）のGSSP 策定に向けた研究が急展開するのに対応し，陸域および海域のセクションにおける放散虫層序の検討を進め，JKB認定に適した放散虫進化系列の探索を進める。海域では太平洋およびインド洋，陸域では日本，中国チベット，イタリアのセクションでの検討を進める。
時代をさかのぼり，エデイアカラ紀からカンブリア紀にかけての地層に対する年代制約結果を投稿する。トアルシアン(178Ma)の海水Os同位体比変動に関しても論文としてまとめる。
