Outline of Final Research Achievements

Boron is used as an important tracer to assess contributions of subduction fluids in arc environments. Because boron analyses using chemical methods have difficulties, prompt gamma ray neutron activation analysis which requires no chemical handling, has been used for boron determination since the 1990s.However, after the nuclear power plant accident in 2011, neutron radiation experiments were halted in Japan. This study developed an analytical method using isotope dilution method for boron in volcanic rocks. The developed method has been successfully applied to the studies on subduction volcanisms in Kyushu island and Chile.

Academic Significance and Societal Importance of the Research Achievements

本研究は火山岩中のホウ素を,正確に比較的簡単な方法で分析する手法を開発した.開発した分析方法は,地球化学の国際学術誌にオープンアクセス文献として公開された.原発事故により放射化分析が難しくなり停止状態であった,ホウ素地球化学の分析研究が再開されるきっかけになることが期待できる.
