贵州省兴义市箐脚金矿床地质特征及找矿前景分析

Geological Characteristics and Exploration Perspective Analysis of Qingjiao Gold Deposit in Xingyi,Guizhou

箐脚金矿床位于雄武背斜近轴部南东翼南西段,金矿赋存于中、上二叠统之间的构造蚀变岩石中。矿体为层状、似层状、透镜状,矿石多为莓状、球状、胶状、环边状结构,星散浸染状、角砾状、晶洞状、薄膜状构造。本文对矿床的成矿地质特征、矿石结构构造、物质组成、蚀变特征等进行分析总结并对矿床成因进行探讨,分析了找矿前景。认为沿已知矿体走向和倾向上加强研究和深部钻探揭露可进一步扩大矿床规模,矿区仍有较大的找矿远景。

Qing Jiao gold deposit is located in the Xiongwu anticline axis near the southeast wing of the southwest section,gold deposit occur in tectonic altered rocks between the middle and upper Permian series.Orebody is layered,stratoid,lenticular,ore is berry shape,jelly,rim like structure,scattered disseminated,brecciform,miarolitic,thin film structure.The metallogenic geological characteristics,ore structure,composition and alteration characteristics of the deposit are analyzed and summarized.The genesis of the deposit is discussed,and the prospecting potential is analyzed.It is believed that along the trend and tendency of the known ore bodies and the deep drilling disclosure can further expand the scale of the deposit,and there is still a great prospect of prospecting in the mine.
