Outline of Annual Research Achievements

本研究課題の最終年度として、これまでの研究成果のとりまとめと成果に基づく今後の研究計画を議論した。研究成果発表として、2020年1月にオマーン王国で開催された国際オマーンオフィオライト会議に続いて、6月のAOGS2020と12月のAGU2020を予定していたが、COVID-19の猛威によってAOGSは中止され、AGU2020はオンライン方式に移行したため取り止めざるを得なかった。国内においては当初5月末に予定されていたJpGU-AGU Joint Meetingが7月にオンライン方式で開催され、本研究課題の成果発表としてICDP Oman Drilling Projectというセッションを立ち上げて20件以上の発表を得た。また、COVID-19によって4月に中止された四国海盆の研究航海が10月下旬から11月上旬にかけて実施され、マドメガムリオンのデタッチメント断層起源と考えられる変形岩を多数採取できたことは、今後の研究に続く重要な成果であった。また、12月に本研究課題の当初の柱としていた前弧マントル掘削計画を実施するための掘削地点周辺の地震探査を実施した。本研究課題は終了するが、前弧マントル掘削計画の実現に向けた基礎研究を続けられる見通しである。11月20-21日に現地とオンラインのハイブリッド方式でワークショップを開催して本研究課題のまとめと今後の研究の方向性について議論できた。現在、本研究課題に関係した学術論文が国内外の専門誌で順次発表されているところであるが、このような成果発表は今後数年間は続くと期待される。全体としてCOVID-19の影響によって研究活動が大幅に制限されたが、本研究課題に必要であったフィールドワークや室内実験のほとんどが前年度までにほぼ完了していたので大きな影響を受けずに無事に終了することができたのは幸いであった。
