摘要
本文通过诸广山岩体、黄龙庙岩体的岩石及其中晶质铀矿稀土元素的研究,得出以下几点认识:晶质铀矿中稀土元素的丰度与其源岩的稀土元素丰度呈正消长关系;晶质铀矿中稀土元素的配分特点与源岩的酸性程度有关;晶质铀矿中稀土元素分馏程度反映了源岩的分异演化程度。
According to the petrological study of Zhuguangshan and Huanglongmiao granites and REE in uraninite from these granites, it can be concluded that REE contents in uraninite and granites are positively correlative; the partition characteristics of REE in uraninite are related to the acidity of initial rocks; and the fractionation degree of REE in uraninite reflects the differentiation degree of initial rocks.
