周家山金矿位于西秦岭多金属成矿带,矿区印支期闪长岩脉大量分布,断裂构造较为发育。结合区域地质特征及对该区地层、构造、岩浆岩、矿体特征等因素进行分析,通过对周家山金矿成矿规律及找矿前景研究,认为该矿床主要受断裂构造与岩浆岩的控制,断裂构造严格控制着矿体的分布,岩浆岩为含金地质体,并且两者叠加部位含矿性好。
The Zhoujiashan gold deposit is located in the West Qinling polymetallic metallogenic belt. Indosinian diorite veins are widely distributed in the ore district, and the fault structure is relatively developed. Based on the regional geological characteristics and the analysis of the stratigraphy, tectonics, magmatic rocks and ore body features in the area, the author studies the metallogenic regularity and ore prospecting of the Zhoujiashan gold deposit, and considers that the deposit is mainly controlled by the fault structure and magmatic rocks The fault structure strictly controls the distribution of ore bodies. The magmatic rocks are gold-bearing geological bodies, and the ore-bearing parts of the superimposed parts are good.
