摘　　要：对采薇海山富钴结壳样品中的伴生有用元素(REE、PGE、W、Mo、Au、Te)的含量变化特征和空间分布特征进行了研究。结果表明:随着水深增加,伴生有用元素REE含量有升高的趋势,Te含量则呈现逐渐降低趋势,PGE、W、Mo和Au与水深、地形之间未能发现明显的相关性;采薇海山伴生有用元素在平面上的分布极不均匀,但多以条带状平行水深等深线分布,也有少数区域表现为斑块状分布,且不同的伴生有用元素的富集区域有所差别。Abundances and spatial distributions of associated useful elements（REE、PGE、W、Mo、Au、Te）in Co-rich Crusts from Caiwei seamount are studied in this paper.The research suggests that REE content rises and Te content decreaces as the water depth increases.The research also indicates that there is no significant correlation between PGE,W,Mo,Au and seafloor topography.Distributions of associated useful elements are highly uneven at Caiwei seamount.But generally,distributions are parallel to the water depth,except that a few areas show patch distributions.Besides,enrichment areas of different associated useful elements are different.
