摘要
根据对中太平洋CC区PC5356孔、PC5362孔及PC5417孔沉积物常量微量元素的测试结果,采用多元统计分析的方法,研究了该地区第四系沉积物中元素含量的空间分布和组合特征,探讨了其物质来源及沉积环境的垂向演变规律。中太平洋CC区第四系沉积物主要为钙质硅质黏土和钙质软泥,早期沉积物受火山活动的影响较大,晚期与生物作用密切相关。
The major and trace elements of sediment samples from PC5356, PC5362 and PC5417 drill cores in the Mid-Pacific Ocean were analyzed, and the result indicates that the contents of elements show three clear changes. Based on a detailed study, this paper discusses the material source of the three drill cores as well as the evolutionary regularity of the depositional environment in vertical direction.
