| 摘 要： | 四川虎牙乡雪宝顶钨锡铍矿床产出宝石级绿柱石、白钨矿、锡石、电气石等矿物且晶形完好.共生矿物有长石、方铅矿、石英、方解石、云母等.绿柱石、白钨矿和锡石色彩绚丽,其成分较为复杂,类质同象现象普遍,晶体形貌具有标型意义.对该区代表性矿物绿柱石、白钨矿、锡石等进行了成分研究、形貌描述及矿物共生组合特点分析,从矿物标型特征、围岩蚀变类型确定了矿床属于高温热液云英岩脉型矿床,在此基础上重点探讨了板状绿柱石成因.

| Abstract: | Many kinds of gem-grade minerals such as beryl, scheelite, cassiterite and tourmaline, and sub-products such as K-feldspar, galenite, tabular quartz, tabular calcite and mica were found in beryl-scheelite vein deposit of Huya, Pingwu County, Sichuan Province. The major minerals like beryl, scheelite and cassiterite have relatively complicated chemical composition and remarkable isomorphism, which enables them to have typomorphic significance. Studies on the chemical composition, configuration and mineral assemblages of the typical minerals such as beryl, scheelite, cassiterite, feldspar and tourmaline of this area reveal the typomorphic significance of the mineral assemblage and it is determined that the deposit is a high temperature epithermal quartz vein deposit. So the appearance of the minerals tabular configuration is concerned with alkali-rich chemical composition, environment of the mineral and the direction of the mineralized hydrothermal liquid. |
