Outline of Research at the Start

北海道中軸部~東部の地質の基本構造や造構史は,1990年代までに一旦確立されたが,2000年以降に中軸部の日高帯を中心に新たな年代値が多数報告され,見直しを迫られている.そこで,本研究では,見直しの遅れている東北海道を含め,岩石学的な再検討や高精度の地球化学データの拡充により,堆積-火成-変成システムが矛盾なく説明できる,北海道中軸部以東の地質体の白亜紀以前から現在までの総合的な観点からの造構史を再構築する.

Outline of Final Research Achievements

Cenozoic magmatic zone from Cape Erimo through the Hidaka Mountains to Kitami City, which constitutes the central axis of Hokkaido, Japan. The authors show that a single geological event, subduction of the mid-ocean ridge, can explain the 46 and 37 million year-old activities, the causes of which were not clearly understood until now. Based on this, together with the addition of detailed age values of sedimentary rocks distributed in the region, we proposed a new geological model for the geological belt in the central axis of Hokkaido from 46 million years ago to the formation of the Kuril Basin at 19 million years ago.

Academic Significance and Societal Importance of the Research Achievements

北海道中軸部には、日高山脈に沿って、日本列島のような島弧のかつての地下深部25 km程度から地表までの地質断面が露出しており、岩石が極めて新鮮で連続的に観察できることから、第一級の研究材料としてこれまでに重要な学術的成果が報告されてきた。ところが、新たな年代測定手法の普及により、これまでの成因を説明するモデルが、新たな年代値によって整合的に説明できなくなってきていた。そこで、当地域の岩石学的・地球化学的・年代学的な新たな視点からの検討を行い、現状の科学的データを説明する新たな地質モデルを構築した。成果は権威のある学術誌に掲載され、国際的に重要な研究対象地域であることが改めて認知された。
