| 摘 要： | 对西南喀斯特地区典型黄壤和石灰土剖面土壤主量和微量元素组成变化特征进行了研究,提供了有关岩石风化和土壤形成过程的信息。所研究的土壤相对于上地壳普遍富集P和Mn,而亏损Na、K、Ca、Mg元素。与黄壤相比,石灰土具有较高含量的K、Rb和较低含量的Sr元素,同时具有较高Th/Ta,Rb/Sr比值和CIA的特征,指示两类土壤成土母质的差别和石灰土较强的风化程度。不同地区同种类型土壤以及同一地区不同类型土壤的化学组成具有显著差别,反映了不同区域和不同类型土壤在成土母质、风化成土过程和程度上的差异。

| Abstract: | Typical yellow and limestone soil profiles in the karst areas of Southwest China,were studied for major and trace element contents,which provides the information about the crustal weathering and soil formation process. The soils studied showed that the contents of P and most Mn in the samples are higher than the average values of upper continental crust (UCC),while the contents of Na,K,Ca,Mg are lower. Compared with the yellow soil profiles,the limestone soil profiles have higher contents of K and Rb,but lo... |
