Outline of Final Research Achievements

In this study, petrological analyses on volcanic rocks from representative active volcanoes and seismological analyses on the crust and mantle were conducted for the Northeast Japan arc and Kurile arc to estimate magma production rates at the representative volcanoes. We have accumulated information about the temperatures and the fluid fractions of the mantle at the depths of the magma generation for many volcanoes, and also obtained high-resolution tomographic images in the NE Japan and Kurile arcs. By combining the results of the petrological and geophysical analyses, we estimated the paths for slab-derived fluids for some volcanoes. However, we cannot complete the estimations of the magma production rates for the representative volcanoes in the three years of the research period, because of the delay of the research.

Academic Significance and Societal Importance of the Research Achievements

本研究において、東北本州弧~千島弧におけるマントル温度構造のリファレンスモデルを提供する準備を整えることができた。このモデルはウェッジマントルの対流モデルの検証や物質循環モデルの構築に役立てることができる。さらに沈み込み帯の研究において残された最重要課題の一つである、ウェッジマントルにおけるスラブ流体の移動経路や移動速度について、重要な制約を得ることができた。また、残念ながら研究期間内では達成することができなかったものの、各活火山で推定されるであろうマグマ生成率は、過去の経験に基づく手法では予測できないケースについても対応できる、中長期的な噴火活動予測の新しい指標として役立てることができる。
