| 摘 要： | 对琉球群岛以东海域134个站位表层沉积物的化学元素含量进行了系统测试,结合矿物学资料等,对研究区的表层沉积物元素地球化学特征进行了分析。结果表明:(1)琉球群岛以东海域沉积物具有半深海沉积物的地球化学特征;(2)通过元素因子分析,把25种元素或氧化物分为4种组合,每一种组合对应不同的物质来源,分别为陆源成因组合(SiO2,K2O,Zr,TiO2,Y,Sc,Na2O,La,Al2O3,P2O5,Ce),生物成因组合(Sr,CaO,L.O.I,CaCO3),火山源成因组合(MgO,V,Fe2O3,Cr,Li,Co),自生源成因组合(Ni,MnO,Cu,Ba);(3)控制本区元素分布的因素主要是水深、物质来源以及生物和铁锰物质的自生作用。

| Abstract: | Based on the analysis results of surficial sediment elements from 134 stations east of the Ryukyu Islands and other mineralogical data,the geochemical characteristics of surficial sediment elements from the study area were analyzed.It is shown from the analysis results that(1) the sediments from the sea area east of the Ryukyu Islands are geochemically characterized by hemipelagic deposits;(2) 25 elements or oxidates can be divided into 4 assemblages,4 assemblages correspond their respective material sources,and they are terrigenous assemblage(SiO_(2),K_(2)O,Zr,TiO_(2),Y,Sc,Na_(2)O,La,Al_(2)O_(3),P_(2)O_(5),Ce),biogenic assemblage(Sr,CaO,L.O.I,CaCO_(3)),volcanogenic assemblage(MgO,V,Fe_(2)O_(3),Cr,Li,Co) and authigenic assemblage(Ni,MnO,Cu,Ba);(3) the main factors governing the surficial sediment element distributions in the sea area are water depth,material source and authigeny of biological and ferromanganese materials. |
