摘    要:光彩石产于福建省南平稀有金属花岗伟晶岩矿田的石英-白云母-锂辉石伟晶岩中与磷锂铝石,天蓝石等紧密共生,是由原生磷锂铝石交代蚀变生成的次生矿物。本文系统地展示了南平光彩石的产状及共生组合、物性及光性特征、化学成分、X射线衍射特征、红外光谱、差热特征等。 指出了光彩石的产出与否是判定伟晶岩稀有金属矿化的标志。

关 键 词:光彩石  铝磷酸盐  花岗伟晶岩  铝磷酸盐矿物  交代蚀变  次生矿化  稀有金属矿化标志

AUGELITE DISCOVERED FOR THE FIRST TIME IN CHINA

Abstract:It was not until 1984 that the first Chinese augelite (Al_2PO_4(OH)_3) was found by the authors in the largest quartz-muscovite-spodumene pegmatite vein at Nanping, Fujian Province. The paragenesis,physical and optical properties, chemical composition, X-ray diffraction pattern, cell dimensions, IR spectrum and DTA curve of Nanping augelite are discribed in this paper. Mineralogical features of Nanping augelite are similar to those of overseas augelites except the occurrence. This work indicates that the occurrence of augelite is an indicator of rare-metal mineralization associated with pegmatites.
Keywords:augelite  Al-phosphate  granite pegmatite  Fujian
