摘要
碲(Te)元素在工业生产中被广泛应用,但在地壳中含量极低,在海洋铁锰结壳中高度富集。评述了海洋铁锰结壳中Te富集过程的相关研究,结果表明:Te在全球海洋中的分布存在空间差异,其中印度洋东经90°海岭铁锰结壳中的Te含量表现出由南向北逐渐升高的特征;铁锰结壳中更古老壳层的Te含量更高,结壳中Te的物质通量会随壳层生长速率的变化而改变;Te以多种形式赋存在铁锰结壳中,且来源具有多源性,主要通过物理过程和化学过程进入结壳。研究有助于促进分散元素海底成矿理论的发展。
The element tellurium is widely used in industrial production,but it is depleted in the earth's crust and riched in oceanic ferromanganese crusts.The authors in this paper reviewed the study about the enrichment process of tellurium in ferromanganese crusts,and it is found that the tellurium content in ferromanganese crusts in various regions is different.For example the tellurium in the E 90° ridge region in Indian Ocean with the increasing trends from north to south.Temporally,the content of tellurium in the old crust is higher,and the tellurium flux would vary with the growh ratios of crusts.The Tellurium element occurs as multi-mineral phases and has multi-sources in ferromanganese crusts,which is controlled by the oceanic physical and chemical process.This research would be beneficial to the development of mineralization theory of dispersed elements.
