摘要
都匀撒朗重晶石矿床位于王司背斜南部,矿体产于桐梓组破碎白云岩中,受层间断裂控制。矿体呈层状、似层状及囊状等。围岩蚀变微弱,为方解石化和硅化。矿石成分简单,主要为重晶石和少量方解石、石英和白云石。矿石构造以脉状构造为主,结构主要为束状结构和不等粒结构。本文通过野外踏勘和室内显微镜下观察对矿床地质特征和控矿因素进行分析,以期为下一步找矿工作提供思路。
Salang barite deposit in Duyun, Guizhou is located in the South anticline of Wangsi. The ore bodies occur in crushing Dolomite of Tongz Formation, controlled by interlaminar fracture. The morphology of ore bodies are stratiform, stratoid and cystic, etc. The Wall rock alteration is weak, including calcitization and silicification. Mineral neral composition is simple, mainly barite and small amounts of calcite, quartz and dolomite. Ore struc- ture is mainly composed of vein structure. The texture is mainly of sheaf texture and heterogranular texture. The field reconnaissance and indoor microscope observation were adopted to analyze the geological characteristics of deposit and ore controlling factors in order to provide ideas for the next prospecting work.
