There are only a few long cores drilled and studied on the outer continental shelf of the East China Sea with water depth more than 50m,core EA01is one of them with many indexes analyzed.The present study mainly utilizes geochemical data to study the sequence and material source of the core.The down core variation of geochemical data is an important index for the sequence and paleoclimate,1 cold event and 3 warm events are identified.Many methods including factor analysis,La/Yb—Ni/Co—Cr/V ternary diagram and U/Th—(Zr+Hf)/(Al_(2)O_(3)+TiO_(2))distribution scatter diagramare used to determine the material source of core EA01,and it is found that the material of core EA01 mainly come from the Changjiang River,which may vary partly according to different climate and environment.
