Abstract

Based on original and literature data, the element composition of ferromanganese nodules from the bottom of lakes and intracontinental and Arctic seas is used for a comparison with nodules in the World Ocean. The main similarities and dissimilarities in the composition of nodules, as well as trends in the accumulation of chemical elements in them, are described. It is shown that high metal contents in the oceanic nodules are related to a relatively higher Mn content therein, which is also partially reflected in marine nodules. Coefficients of the correlation between elements in the entire sample set with diverse correlations are determined. High contents of some metals in the Arctic nodules are comparable with their average contents in the oceanic nodules, indicating local metal concentrations in ferromanganese formations in the East Arctic. Nodules are highly enriched in manganese and iron oxides (26.7 and 53.1%, respectively) relative to sedimentary rocks. At the same time, they are depleted in all other macroelements except P.

海洋和湖泊中锰铁结核中元素的分布

摘要

根据原始和文献数据，将湖泊底部，洲际和北极海域的锰铁结核元素元素与世界海洋中的结核元素进行比较。描述了结核组成中的主要异同，以及其中化学元素的积累趋势。结果表明，海洋结核中较高的金属含量与其中相对较高的锰含量有关，这也部分反映在海洋结核中。确定具有不同相关性的整个样本集中的元素之间的相关性系数。北极结核中某些金属的高含量与海洋结核中的平均含量相当，这表明东北极的锰铁地层中局部金属浓度较高。相对于沉积岩，结核中的锰和氧化铁含量很高（分别为26.7和53.1％）。同时，它们除P之外的所有其他宏观元素都已耗尽。
