以白银市羊圈沟铜金矿为例,论述了区域地质背景,认为该铜金矿床的物质来源与钠长岩有关,矿体严格受钠长岩控制,与围岩界线清楚,钠长岩脉的结构构造与斜长花岗岩相似,通过铜金矿床特征对比,矿体形成于岩浆结晶晚期,残余岩浆沿构造带贯入并形成中低温热液矿床。总结了找矿标志,对找矿前景进行了分析。
Taking the Yukougou copper-gold mine in Baiyin City as an example, the regional geological background is discussed. It is concluded that the material sources of the copper-gold deposit are related to albite. The orebody is strictly controlled by albite and has a clear boundary with surrounding rock. The structure of the vein is similar to that of plagiogranite. According to the characteristics of the copper-gold deposit, the ore body is formed in the late stage of magma crystallization, and the residual magma penetrates along the tectonic belt and forms the middle-low temperature hydrothermal deposit. Summarized the prospecting signs, prospecting prospecting was analyzed.
