海洋锰结核是当今举世瞩目的海底矿产资源,它的开发和利用不仅会改变世界金属供求的现状,而且对今后相当长的时期内人类物质文明的发展也将产生影响,锰结核的外部形态和宏观构造是人们早就知道的(图1A、B为两枚深海锰结核的外形)。但其内部的矿物晶体结构和元素存在状态则是一个很复杂的问题,在国外已经做了多年工作,至 Marine manganese nodules are the world’s most notorious seabed mineral resources. Its development and utilization will not only change the status quo of world metal supply and demand, but also have an impact on the development of human material civilization for a long period in the future. The external forms of manganese nodules and Macroscopic structures have long been known (Figure 1A, B is the shape of two deep sea manganese nodules). However, its internal mineral crystal structure and the presence of elements is a very complex issue, has been done in foreign countries for many years to
