用电子探针分析了三个土壤结核和一个铁盘中的Al、Si、Ti、V、Mn、Fe、Co、Ni、Cu和Zn元素。从表面分析看来，结核由两个主要富集区组成，即富锰、富铁区和第三个低锰、低铁区。Co、Ni、Cu和Zn元素在第一带富集，而钒在第二带富集。在铁盘中可区分出富Ti、富Fe、富Ti和富Fe四个富集带和一个低Ti和低Fe区。金属锰、钴、镍、铜和锌主要富集在富钛铁区。从物理化学因素的角度讨论了微量元素与结核和铁锅主要成分的关系。
Three soil nodules and an iron-pan have been analysed for the elements Al, Si, Ti, V, Mn, Fe, Co, Ni, Cu and Zn using an electron microprobe. From the surface analysis it appears that the nodules consist of two major concentration zones of enrichment, viz. Mn-rich, Fe-rich zones and a third zone low in Mn and Fe. The elements Co, Ni, Cu and Zn are enriched in the first zone, whereas vanadium is enriched in the second zone. Four concentration zones are distinguishable in the iron-pan, Ti-rich, Fe-rich, Ti and Fe-rich and a zone low in Ti and Fe. The metals Mn, Co, Ni, Cu and Zn are mainly enriched in the Ti/Fe-rich zone. The associations of the trace elements with the major components of the nodules and iron pan are discussed in terms of physico-chemical factors.
