据最近分析,查出锰结核中含有56种元素(据Mckelvey,1983).其中品位在0.01%以上的28种.从下表可以看出,含1.8%~1%高品位的元素有Mn、Fe、Si、Al、Ca、Na、Mg;此外属于微量成分的,含1%~0.1%的有Cl、K、Ti、Ni、S、Cu、P.C、Co、Ba、Zn;含0.1%~0.01%的有Pb、Sr、Ce、Zr、V、Mo、Nd、La、Y、Li等元素.这些元素在地壳中的平均品位与在锰结核中所占品位相比较,从富集比来看,可知Mn、Ni、Cu、Co、Pb、Mo等金属元素正以253倍至74倍,Zn以17倍的比例富集于锰结核中.但是,锰结核的化学组成并非各处都是一样,据说与产地、产状、形态类型等方面的变化有关,即使是区域比例或结核内部显微镜下比例也有很大变化.象这样的化学组
According to a recent analysis, it was found that there are 56 elements in manganese nodules (Mckelvey, 1983), of which 28 are above 0.01%. As can be seen from the table below, elements with a high grade of 1.8% to 1% K, Ti, Ni, S, Cu, PC, Co, Ba and Zn with 1% ~ 0.1% 0.01% of the elements are Pb, Sr, Ce, Zr, V, Mo, Nd, La, Y, Li, etc. The average grade of these elements in the crust is comparable to the grade in manganese nodules, It can be seen that Mn, Ni, Cu, Co, Pb, Mo and other metal elements are 253 times to 74 times, Zn is 17 times the concentration of manganese enrichment in the nodules. However, the chemical composition of manganese nodules is not everywhere Similarly, it is said that it is related to changes in origin, origin, type of morphology and the like, even in the area ratio or in the ratio of the internal microscope of tuberculosis.
