Outline of Final Research Achievements

We conducted various surveys, including heat flow measurements and analysis of pore water extracted from sediment samples, on the Pacific plate seaward of the Japan and Kuril trenches. We obtained valuable new data on fracturing of oceanic crust due to plate bending and associated fluid, heat and material flows. They revealed that the fracturing process and flow patterns are different between the Japan and Kuril trenches, vary along the trench axis and are highly heterogeneous at a scale of several km. The data obtained in the vicinities of normal faults on the seaward trench slope indicate development of fractured zones and fluid circulation reaching deeper part of the crust.

Academic Significance and Societal Importance of the Research Achievements

海溝に沈み込む前の海洋地殻内での水・熱・物質の動きについて得られた結果を用いることで、沈み込みプレート境界付近の温度構造や水分布の精度のよい推定が可能となる。これは、沈み込み帯に関する幅広い分野の研究において基礎的な情報となるものである。また、海溝による違い、同じ海溝の中での地域による違いを明らかにしたことは、海溝陸側での地震発生や変形過程、島弧の地球化学・岩石学的な特徴、等の地域性の要因の解明に寄与するものと期待される。
