对东海陆架北部泥质区的FJ04孔进行了元素含量分析、粒度分析以及AMS14C测年,讨论了元素含量与沉积物粒度的关系,采用R型因子分析讨论了元素间的组合关系.研究表明,近3ka来FJ04孔元素含量稳定,大部分元素含量随沉积物粒径变细呈增加趋势,Ca和Sr的含量呈减少趋势,Ba、Th和P与沉积物粒径的相关性很差.因子分析结果表明,FJ04孔元素含量变化是“元素粒度控制”、自生钙质组分加入、海水和孔隙水影响、源区风化程度以及沉积环境氧化还原状态等综合作用的体现.“,”Based on the data of AMS 14 C dating,grain-size analysis and XRF analysis of Core FJ04 from the northern part of the East China Sea,using R-factor analysis as a tool,this paper discussed the relation between grain-size and elements,and the relation among elements.The results show that contents of most elements increased with grain-size decrease,except Ca and Sr,even the change is little during the last 3ka.However,poor correlation exists between grain-size and contents of Ba,Th and P.Factor analysis demonstrates that the contents of elements depend upon grain-size,input of biogenetic calcium carbonate,influence of sea water and pore water,the weathering intensity of parent rocks and the redox process in the depositional environment.
