| 摘 要： | 稀土元素广泛地应用于研究不同地质体的同源性判断方面。通过小西林和绰尔水系沉积物和不同层位土壤中稀土元素地球化学特征研究,发现不同粒级( 80目和-80目)的泥炭均具有“Ce亏损型“配分模式,土壤残积层和坡积层的配分模式基本上相同,表明它们来自同一类母体;腐殖层土壤和水系沉积物细粒级(-60目)的配分模式与泥炭基本相同,表明腐殖层土壤是泥炭的重要供给源;水系沉积物细粒级(-60目)部分则主要来自泥炭。

| Abstract: | REE tracing has been widely used to the co-origin judgment of geological bodies. A study on geochemical characteristics of REE in stream sediments and soils of different layers in the Xiaoxilin and Chao'er areas has been made. It is shown that the peat of both meshes 80 and-80 appears as in the partition pattern of "Ce-depletion", and the similar pattern could be found in residual soil and clinosol, indicating they are from the same parent. While the partition pattern of the humic soil and the stream sediments of -60-mesh is also basically the same as that of peat, indicating that the humic soils are the important supplying source for the peat, while the sediments of fine grade (-60-mesh) is mainly from the peat. |
