摘　　要：辉锑矿是湖南锡矿山锑矿床最主要的矿石矿物 ,通过野外地质调查和系统的室内矿物学研究表明 :辉锑矿晶体形态特征受晶体生长方向和生长速度影响 ;辉锑矿的常量元素和微量元素化学成分分析揭示了成矿溶液的某些信息 ,并有助于评价不同类型的矿石质量 ;随早世代到晚世代 ,辉锑矿晶胞参数变大 ,与其类质同像元素含量增大相一致 ,由ao 值求得辉锑矿的形成温度为 2 5 0℃～ 10 0℃ ;此外 ,还获得了辉锑矿反射率光谱图、光性特征、非均质旋转角等可靠的矿物学数据。Detailed field geology and mineralogy investigations have been made on the stibnite which is the most important ore minerals in Xikuangshan antimony deposit, Hunan Province. The results show that stibnite crystal morphology is affected by its growth directions and growth rate. The chemical compositions of main and minor elements of stibnite reveal some valued information on mineralizing solution, and reflect quality of three ore types. Stibnite cell parameters are increasing with the generation from early to late, which is correspond with varying of isomorphous element contents. According to cell parameter ao value, the forming temperature of stibnite is from 250℃ to 100℃. In addition, valued mineralogical data of stibnite such as reflectance spectrum, optical sign, anisotropism rotational angle are obtained. The results of this research provide important information on typomorphic characteristics of stibnite, valuing of ore quality and multipurpose use.
