Using europium (Eu) redox state to trace the evolution of seawater chemistry ...

The aim of this study is to determine the redox state of Eu hosted in banded iron formations (BIFs) deposited on seafloor at different times of the Earth’s history using XANES....本研究旨在利用X射线吸收近边结构谱（XANES），测定地球历史不同时期海底沉积的条带状铁建造（BIFs）中赋存的铕（Eu）的氧化还原状态。
