| 摘 要： | 通过对新疆彩霞山铅锌矿床不同类型岩石和矿石的稀土元素地球化学特征的研究,探讨了岩石和矿石中稀土元素地球化学行为。结果显示,矿床中稀土元素的分布是不均匀的。在稀土元素配分模式上,活化的白云石大理岩与矿石是相近的,具有显著的δEu正异常和弱的δCe负异常,表明成矿与白云石大理岩的关系密切。同时,根据稀土元素特征的变化,提出了矿床的形成可能与岩浆活动有关的研究思路。

| Abstract: | Through the geochemical analysis of the rare earth elements in different types of rocks and ores from Caixiashan Pb-Zn deposit, the geochemical behavior in rocks and ores of rare earth elements is researched. The results show that the distribution of rare earth elements in this deposit is inhomogeneous. The rare earth element pattern of activated dolomite marbles are similar to that of ores which is characterized by remarkable δEu positive anomaly and weak δCe negative anomaly, which indicates that the mineralization has close relation to the dolomite marble. At the same time, the authors consider that the formation of the deposit may he related with the magmatic activity, according to the variation characteristics of rare earth elements. |
