摘要
上宫金矿田是豫西著名的黄金生产基地,近年在该区开展了一系列找矿勘查工作,取得了较好的找矿效果。该区金矿床受断裂构造控制明显,通过几何特征、力学性质、期次划分对断裂构造进行解析,分析了矿床构造控矿特征:矿体分段富集、构造叠加控矿、北东向构造矿体走向延长大于倾向而南北向构造反之。根据矿床构造控矿特征,指出F1的深部、F1走向上中浅部及一系列尚未突破的南北向构造具有找矿潜力。
Shang-gong gold field is the famous gold production base in Western Henan.In recent years,we have carried out a series of prospecting and prospecting work in this area,and achieved better prospecting results.The gold deposits in this area are obviously controlled by faults.This paper analyze fracture structure through geometry,mechanical properties stage division,and analyze the characteristics of ore controlling structure of the deposit： stepwise enrichment,ore controlling tectonic superposition,trend of ore in NE structure to extend more than inclination,inclination of ore in NS structure to extend more than trend. According to the ore controlling characteristics of the ore deposits,it is pointed out that： the deep of F1 and the middle and shallow parts of F1 trending upper,as well as a series of NS structures which have not yet been broken,have great potential for prospecting.
