Outline of Final Research Achievements |
Major factor for the chemical heterogeneity of the Earth’s mantle is the global water cycle of the Earth’s interior. In the previous works, this issue was discussed using volcanic rocks (volcanic glasses and melt inclusions), which is the melting product of mantle. In this study, we developed the analytical methods for measuring the trace amounts of water, fluorine, sulfur and chlorine in the mantle minerals (olivine), and established a system to collect volatile data from mantle minerals.

Academic Significance and Societal Importance of the Research Achievements |
鉱物中の極微量な揮発性物質濃度を高精度、高分解能で量産ができるようになった。今後は海洋島火山のマントル捕獲岩に限らず、中央海嶺、島弧、大陸など様々なテクトニックセッティングに産するかんらん岩に含まれるマントル鉱物に応用することが可能になり、玄武岩ガラス中の揮発性物質とマントル鉱物中の揮発性物質の両方の研究からアプローチして地球内部の水循環に制約を与えていくという新しい研究を展開することが期待できる。
