| [摘 要] 福建武夷山上西坑钼矿为中温热液型钼矿。文章根据野外考察，在岩相学的基础上，进行了矿相学及辉钼矿矿石矿物学的系统研究，得出上西坑钼矿矿石自然类型主要为构造角砾岩型、石英脉型。矿石构造主要有角砾状、浸染状构造、细脉状构造。矿石结构以细-中细粒鳞片结构为主，局部呈现厚板状、带状分布；矿石矿物辉钼矿铅灰色，多色性明显，2H多型，矿物成分中杂质含量较低，Re含量为1.479-34.35ug/g，显示其矿源为壳幔混合源；Re作为伴生矿产，具一定的综合利用价值。 |

| Abstract: The Shangxikeng molybdenum deposit in Wuyishan, Fujian Province is a medium hydrothermal type deposit. Based on field investigations and ore mineralogical studies, this paper researches the characteristics of ore petrology and mineralogy of molybdenite in the Shangxikeng molybdenum deposit. The results show that the main ore natural types are structural breccia type and quartz vein type. The ore structures include breccia , disseminated and small vein structures. The ores mainly display fine-medium fine grained platy texture with few thick tabular texture. The ore minerals (only molybdenite) are leaden in color, and show obvious polychroism and 2H polymorph. The mineral is low in impurity content, and the content of Re is 1.479-34.35Ug/g, indicating the ores originate from a crust-mantle mixed source. As a kind of associated elements, Re is of some comprehensive utilization value. |
