本文通过东太平洋海盆、中太平洋海盆锰结核、云南东南部土壤锰结核及原生沉积锰矿特征及形成环境的对比研究,表明:(1)海洋水深,地形、生物生产力与水—沉积物界面的Eh、pH值等是控制锰结核物质成份、生长速率及分布格局的重要因素,(2)南极底层流和深海沉积间断的形成发展是造成锰结核生长间断的关键,(3)新生代低海平面时期可能是锰结核生成的重要时期。 In this paper, the characteristics of the marine manganese nodules and the primary sedimentary manganese deposits in the eastern Pacific Basin, the Central Pacific Basin manganese nodules and the southeastern Yunnan Province are compared and studied. The results show that: (1) the relationship between ocean depth, topography, bio-productivity and water-sediment interface Eh (2) The formation and development of the intercontinental bottom flow and deep-sea sedimentary discontinuities is the key to the intermittent growth of manganese nodules, (3) The low-sea level of Cenozoic The period may be an important period for the generation of manganese nodules.
