(Table 2) Concentrations of >0.05 mm size fraction micronodules in sediments of the Clarion-Clipperton province and chemical composition of these micronodules and sediments@en

Analysis of contribution of micronodules of sand and silt size to chemical composition of various types of pelagic sediments, as well as use of published data indicate that in some types of bottom sediments micronodules are the principal carriers of manganese and nickel. These elements appear to constitute smaller fractions of colloidal iron and manganese hydroxides, as well as terrigenous material.通过分析砂级与粉砂级微结核（micronodules）对各类远洋沉积物（pelagic sediments）化学成分的贡献，并结合已发表的数据，可证实：在部分类型的底沉积物中，微结核是锰与镍的主要载体。上述两种元素在胶体铁锰氢氧化物与陆源物质中仅占较小比例。
