摘要：

Three soil nodules and an iron-pan were analyzed for the elements Al, Si, Ti, V, Mn, Fe, Co, Ni, Cu and Zn using an electron microprobe. From the surface analysis the nodules apparently consists of 2 major concentration zones of enrichment, viz. Mn-rich, Fe-rich zones and a 3rd zone low in Mn and Fe. The elements Co, Ni, Cu and Zn are enriched in the 1st reich zone, whereas V is enriched in the 2nd 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.
