利用80年代,特别是90年代以来研制的太平洋锰结核及深海沉积物标准物质的有关资料,统计计算获得了太平洋锰结核及深海沉积物中包括主量、次量和痕量共70个元素的平均化学组成新数据,并将这些数据与Cronan等人的相关数据作了对比。用这些新数据计算的锰结核及沉积物70个元素的百分含量总和分别为99.9％和99.7％。
Based on the data of the standard materials of Pacific manganese nodules and deep-sea sediments developed in the 1980s, especially in the 1990s, a total of 70 elements including major, minor and trace elements in the Pacific manganese nodules and deep-sea sediments were calculated Average new chemical composition data and compare these data with Cronan et al.’s data. The sum of the percentages of 70 elements of manganese nodules and sediments calculated with these new data is 99.9% and 99.7%, respectively.
