微量元素在海洋沉积物中含量、分布的研究对于揭示海洋中物质的运动规律,沉积组成及变化,海洋与陆地的关系,海底沉积物与覆盖水之间的关系,了解元素之相关性,沉积来源,元素的富集系数与滞留时间等等有着直接的关系,故受到国内外海洋地质工作者的关注。为了保证海洋沉积物中微量元素的分析准确度,国际原子能机构(IAEA)1984年研制成了代号为SD-N-1/2的细粒天然沉积物供各实验室间及不同实验方法比对分析用。样品采自北海
The study on the content and distribution of trace elements in marine sediments reveals the relationship between elemental relativity, sedimentology and sediment-water correlation in order to reveal the laws of movement of materials in the ocean, sedimentary composition and variation, the relationship between oceans and terrestrial, Source, element enrichment coefficient and residence time has a direct relationship, it is subject to the attention of marine geology workers at home and abroad. In order to ensure the accuracy of the analysis of trace elements in marine sediments, the International Atomic Energy Agency (IAEA) developed the fine-grained natural sediment code SD-N-1/2 in 1984 for comparison among laboratories and different experimental methods Analysis.
