| 摘 要： | 研究江淮地区白浆土铁锰结核的重量分布、颜色及其地球化学特征．结果表明：在白浆层中结核含量最高且多具有同心圆结构；结核颜色和形状决定于颗粒的大小；在结核中发生了Ｓｉ、Ｆｅ、Ａｌ和Ｍｎ的富集，其它元素则与土壤相近．可以断定，铁锰结核是在白浆化过程中就地形成并累积的．

| Abstract: | In this paper, the weight distribution, the colours and the element geochemistry characteristics of Fe-Mn nodules are studied. There are many nodules in albic horizons, and most of these nodules have concentric structures. The nodules colours and forms depend on their sizes; Si, Fe, Al and Mn concentrate in nodules, Other elements are similar to those in albic soils. It is concluded that Fe-Mn nodules formed in albic processes and accumulated in the original places without being transported. |
