Chemical and mineral compositions of bottom sediments and ferromanganese crusts and nodules near Iceland

Results of study of bottom sediments near Iceland and on the Jan Mayen Island are reported. It was found that in recent sediments chemical elements are mainly associated with pyro- and volcanoclastics. In some areas adjusted to deep-seated faults ancient iron-manganese crusts and sediments occur. They are rich in Ni, Co, V, Cu, Mo, Cd and other elements associated with endogenic matter.

本文报道了冰岛附近及扬马延岛（Jan Mayen Island）周边海底沉积物的研究成果。研究发现，近代沉积物中的化学元素主要与火山碎屑（pyroclastics）及火山碎屑岩（volcanoclastics）相关联。在部分毗邻深大断裂的区域，分布有古铁锰结壳及相关沉积物。这类结壳与沉积物富含镍（Ni）、钴（Co）、钒（V）、铜（Cu）、钼（Mo）、镉（Cd）等与内生物质相关的化学元素。
