| 摘 要： | 本文采用晶体场谱、穆斯堡尔谱、红外光谱和X射线衍射等多种手段研究褐帘石的谱学特征。从而探讨其结构特性,形成条件,岩体演化与稀土元素演化的关系。认为本区的褐帘石是部分变生的。变生的机理是因为其晶格中含放射性元素U,Th高,且这与褐帘石的选矿性能有重要关系。

| Abstract: | X-ray diffraction, infrared spectrum, Mossbauer spectrum, and absorption spectrum have been used to study allanite in some rare-earth deposit in this paper. The results show that the allanite is partly-metamict, which was caused by the radioactive decay of Th, U existing in the lattice of allanite. The crystal-chemical properties and the genesis of the allanite have been disscussed, in addition, the radioative decay of Th and U and the oxidation cause rare-earth elements to be released from its lattice to develop the ion-absorbing weathered crust deposit of rare-earth elements, which has important significances in the ore dressing of allanite. |
