在地质作用过程中,化学性质极其相似的稀土元素(REE)往往是作为一个整体活动的。但是,由于它们性质上的微小差异,却发生了一定的分异,这种分异特征是受外界条件控制的,我们可以通过研究地质体中REE的组成特征来探讨许多地球化学问题,特别是最近有越来越多的学者用来讨论某些岩石和矿床的成因和演化。
In geologic processes, rare earth elements (REEs) with very similar chemical properties tend to be active as a whole. However, due to their slight differences in nature, some differences have taken place. This differentiation is controlled by external conditions. We can explore many geochemical issues by studying the compositional features of REEs in geologic bodies. In particular, More and more scholars have recently been used to discuss the genesis and evolution of certain rocks and deposits.
