Outline of Final Research Achievements

Nasca Plate having relatively younger age subducts southern Chile Trench. On this province, obvious fracture zones ( liner altered zones) formed in the plate are recognized on recent submarine topography. In this study, we have revealed that volcanic rocks composing of the Quaternary arc-volcanoes above the subducted fracture zones in the plate were so far more enriched in hydrophile elements (for example, Cs, Rb, ba, K, Pb, Sr, Sb,etc) than those in the volcanoes above the non-fracture zone in the plate. This fact suggests that fluids from the subducted fracture zones were more enriched and degree of partial melting of the mantle wedge beneath the Quaternary volcanoes were increased, as a result, the Quaternary volcanoes above the subducted fracture zones to be recently more active.

Academic Significance and Societal Importance of the Research Achievements

今回,南部チリ弧に分布する島弧火山帯において,沈み込む海洋プレートに発達する断裂帯直上の第四紀火山の島弧火成活動は通常の地域の火山に比べ流体の付加が増大し,活発化していることが明らかになった.南部チリ弧では比較的若い海洋プレートが沈み込んでいるため,海底地形から破砕帯の位置は明瞭に把握できるが,古い海洋プレートが沈み込んでいる東北日本弧や伊豆―小笠原弧ではその上に厚い堆積物が覆っているためその位置は明確でない.しかし,今回得られた地球化学的解析法を駆使すれば,環太平洋火山地帯全域の第四紀火山において,どの火山が今後活発化するか推定できうる重要な基礎データになる可能性がある.
