稀土元素在物源分析研究中的应用——以鄂尔多斯盆地上古生界为例

The Appliance of Rare Earth Element in the Study of Provenance Analysis——With the example of Ordos basin in Neopaleozoic

沉积物的元素地球化学性质是复杂的,影响和控制元素地球化学性质的过程也是多种多样的。在影响元素分布规律的各种因素中,物源区母岩性质对某些元素的分布规律有着直接的影响,特别是对那些稳定性较大的元素,稀土元素(REE)具有相对的稳定性。利用这一特性,在有效误差范围内,可以适当应用于物源分析解释。

The geochemical nature of the element of sedimentary is complex, and the process which controls and influences the geochemical nature of the elements is also various. In the factors impacting the distribution rule of elements, the nature of the native rock in provenance directly impacts the distribution rule of some elements, especially for some elements whose stability is better. REE has relative stability. In the extension of inaccuracy, using the character, we can use it for the explaining of the provenance analysis.
