Outline of Final Research Achievements

We measured the radiocarbon ages of organic compounds in lake sediments of Fuji Five Lakes (Lakes Kawaguchi and Yamanaka) to elucidate high-resolution eruptive history of Mount Fuji, the largest basaltic stratovolcano in Japan. We found that the age of lake sediments can be determined precisely using fatty acids even in the sediments that contain no plant macrofossils. We also developed the age-depth model of Lake Yamanaka sediments, which revealed the detailed ages of volcaniclastics in the sediments over the past 8000 years.

Academic Significance and Societal Importance of the Research Achievements

湖底堆積物を使うことで、陸上に比べより正確な火山噴出物の堆積年代を明らかにできることが示された。また、湖底堆積物中には従来陸上では報告されていない火山噴出物が多数含まれていることが明らかとなり、高頻度で噴火を繰り返す玄武岩質火山の噴火履歴の解明に湖底堆積物が極めて有用であることが明らかとなった。今後、富士五湖の湖底堆積物中の火山噴出物の分析を進めることで、富士山の噴火履歴の解明がより一層進むことが期待される。
