南平花岗伟晶岩中铯沸石的研究

Study on the Pullucite in Granitic Pegmatites in Nanping, Fujian Province

目前在中国已发现两种铯矿物，即南平石和铯沸石，其中铯沸石主要分布在新疆、陕西、河南省的花岗伟晶岩中，在华南，南平花岗伟晶岩是迄今所报道的铯佛石的唯一产地。我们将南平铯沸石分成原生和次生两类，本文详细报道了南平铯沸石的产状、物性和光性、化学成分、Ｘ射线衍射特征、红外光谱、差热分析和形成过程。

wo caesium-bearing minerals have been discovered in China, which are nanpingite and pollucite. The pollucite mainly exists in the granitic pegmatites in Xinjiang, Shanxi and Henan provinces in China, but so far, in South China the pollucite comes from The Nanping granitic pegmatite. The Nanping pollucite can be divited into two kinds (primary and secondary). The paper focuses on the discussion of the analysis results of the Nanping pollucite, such as pollucite occurrence, physical and optical properties, chemical compositions, X-ray diffraction pattern, IR spectrum, DTA-TGA curves and its genesis.
