对中国多金属结核开辟区沉积物的详细研究表明 ,研究区内沉积物处于氧化至弱氧化环境 ,两种色调的沉积物在粒度分布特征以及化学组成上都存在着显著的差异 ,它们是不同沉积环境的反应 .不同色调之间的界面为一沉积间断面 .沉积物中的铁和锰具有不同的来源 ,铁可能以岩源碎屑为主 ,而锰则更可能是自生成因 .钙和镁以生物成因为主 .
A detailed study of the sediments in the China polymetallic nodules has shown that the sediments in the study area are oxidized to a weakly oxidizing environment and that the sediments of the two hues have significant differences in particle size distribution characteristics and chemical compositions, Sedimentary environment reaction. The interface between different shades is a sedimentary discontinuity. The sediments have different sources of iron and manganese, iron may be mainly rock debris, and manganese is more likely to be self-generated calcium and Magnesium causes biological mainly.
