Geochemical Characteristics and Their Implications to Provenance and Environment of Surface Sediments from the South Okinawa Trough

Institute of Oceanology, Chinese Academy of Sciences, Qingdao Shangdong 266071

摘要

摘要: 对冲绳海槽南部陆架、陆坡和海槽 33个表层沉积物进行了元素地球化学分析,结果表明研究区沉积物的主要化学组成为SiO₂ 、Al₂ O₃ 和CaO,这三种组分占沉积物总量的 6 8%左右。多数元素在陆架和陆坡的变化范围较大,在海槽区相对稳定。向海槽方向随沉积物粒径变细,SiO₂ 和CaO减少、Al₂ O₃ 和其它多数元素含量增加。常量元素和Al₂ O₃ 的比值分布特征表明,本区沉积物由物源区经由陆架向海槽输送,沉积物主要由陆源碎屑沉积组成,此外还有生物碎屑沉积和自生沉积。陆架区部分微量元素富集因子 (EF)与长江和黄河沉积物的富集因子对比结果表明,本区的沉积物与长江沉积物的关系更为密切。陆坡区Cu、Pb、Zn、Co、Ni和Cr的富集因子较高是由于生物的富集作用造成的,Mn的富集主要是自生沉积的结果。用R型因子分析方法对沉积物的化学组成进行了分析,结合元素的分布特征,给出了四个主因子所对应的沉积环境和特征元素组合,分别为 1)陆架型的元素组合 :SiO₂ 、TiO₂ 、Zr、CaO和Sr,2 )陆坡型的元素组合Fe₂ O₃ 、MgO和P₂ O₅,3)海槽型的元素组合 :Al₂ O₃ 、K₂ O、Cu、Zn、Co、Ni、Cr和Ba,4 )反映沉积环境氧化—还原属性的元素组合 :MnO和FeO。

Abstract: Chemical compositions of 33 surface sediment samples were measured.The samples were collected from the continental shelf, slope and the south Okinaw a Trough, respectively.The major chemical compositionsare dominantly composed of SiO₂, CaO and Al₂O₃, w hich account for about 68 percent weig ht of the sediments.Most of the elements change w ith a w ide range in the shelf and slope sediments, but keep stable in the trough sediments.From shelf to trough, the g rain size of the sediment becomes finer, at the same time, the content of SiO₂ and CaO decrease, and the content of Al₂O₃ and most of other elements increase.Based on the dist ributions of the major elements/ Al₂O₃ ratio, it can be concluded that the sediments are transported from the provenance area to the trough.The sediments mainly composed of terrigenous, biogenic and autogenetic deposits in the study area.Comparing the enrichment factors (EF )of some element s of the shelf sediment swith the Yang tse River and Yellow River sediment s, It can be concluded that the sediments in the study area are similar to the Yang tse River sediments.The high enrichment factors of Cu, Zn, Pb, Co, Ni and Cr in the slope are caused by the biogenic enrichment.The enrichment of Mn is caused by autogenetic deposit.Based on the R -mode factor analy sis of the chemical compositions, combined w ith analysis of the distributions of the elements, four major facto rs indicate four sedimentary environments respectively.Every sedimentary area has its own typical elements group.They are, 1)Shelf-type elements group :SiO₂, TiO₂, Zr,CaO and Sr;2)Slope-type elements group :Fe₂O₃,MgO and P₂O₅;3)Trough-type elements group :Al₂O₃, K₂O, Cu, Zn, Co, Ni, Cr and Ba, and 4)Redox elements group :MnO and FeO respectively.
