過去400万年間に起こった地磁気逆転の年代確定と生物相・気候に対する影響の検証

日本学術振興会:

Project Year: Apr 2019 - Mar 2023

本研究では,堆積速度が速く安定した古地磁気シグナルを持ち,微化石産出が良好な海成層を用いることで,過去400万年間に起こったほぼ全ての地磁気逆転記録を超高解像度で復元することを目的とする.そのために,1)古地磁気および10Be測定を併用することで地磁気逆転に伴う磁場方向および強度の変化を求め,2)逆転層準を含む周辺層準の連続した酸素同位体記録およびテフラ層の放射年代から地質年代を確定することで,地磁気逆転のタイミング・継続期間を明らかし,3)花粉・海洋微化石群集解析を行うことで,地磁...
