Abstract

Abstract

The total content of rare earth element(∑REE)ranges from 123.45 to 187.12 μg/g in sediments of HY126EA1 hole.The average content of ∑REE is 164.07 g/g,approaches the average content of ∑REE in sediments in the world,and is similar to that of surface sediments in the Huanghai Sea,the Bohai Sea and the East China Sea.The change trend of standard curves of ∑REE has no difference in various types of sediments,and the same kind of sediment at different time.It suggests that the sediments of HY126EA1 hole come from the same material source.∑REE,Eu and Ce have obvious change in vertical,which may reflect the stage change of climatic environment in sediment source area.
