西华山钨矿是一个产于燕山期花岗岩中的大脉型钨矿床。矿脉最长可达1 075 m,最大厚度3.6m,最大延深在350 m以上。从矿床上部至下部大致相应可分为4个成矿阶段:硅酸盐阶段→氧化物阶段→硫化物阶段→碳酸盐阶段。利用红外显微镜及其它相关设备,对矿床不同中段共9组样品中共生透明矿物(石英、绿柱石和萤石)与不透明矿物(黑钨矿、黄铁矿)以及明显受应力作用和流体改造程度不同的3种石英(水晶)与共生黑钨矿的流体
Xihuashan tungsten deposit is a vein type tungsten deposit produced in Yanshanian granite. The longest veins up to 1 075 m, the maximum thickness of 3.6 m, the maximum depth of 350 m or more. From the upper part to the lower part of the deposit, there are roughly four ore-forming stages: Silicate stage → Oxide stage → Sulfide stage → Carbonate stage. Using infrared microscopy and other related equipment, a total of 9 samples of different mineral deposits in the middle of the group of symbiotic transparent minerals (quartz, beryl and fluorite) and opaque minerals (wolframite, pyrite), as well as the apparent stress and fluid modification degree Different three kinds of quartz (crystal) and symbiotic Wolframite fluid
