摘要采用火花源质谱法对Allanton附近的四种黄灰色土壤（两种Fragiaquepts和两种Fragiochrepts）的悬链线序列中的铁锰结核及其周围土壤样品进行了分析。提供了12种稀土元素（La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er和Yb）和5种其他稀土元素（U、Th、Pb、Cs和As）的数据。稀土元素显示很少或没有富集结核相对于周围的土壤，这是符合相对较低程度的富集锰结核。As、Pb和Th在所有结核样品中都富集。
Abstract Analyses of samples of iron-manganese concretions and their surrounding soil materials, from a catenary sequence of four yellowgrey earth soils (two Fragiaquepts and two Fragiochrepts) near Allanton, have been carried out using spark source mass spectrometry. Data are presented for 12 rare earth elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, and Yb) and 5 others (U, Th, Pb, Cs, and As). The rare earth elements show little or no enrichment in the concretions relative to the surrounding soil and this is consistent with a relatively low degree of enrichment of Mn in the concretions. As, Pb, and Th are enriched in all samples of concretions.
