郭城断裂带作为郯庐断裂的次级导矿构造,控制着该地区金矿床的分布和产出,并且金矿床还受胶莱盆地边缘层间滑动构造的控制,金矿成矿的地质背景和构造特殊. 从区域成矿背景和矿床特征入手,分析了郭城断裂带金矿床的找矿潜力及找矿方向. 分析结果表明,郭城断裂带深部存在含矿大岩体,具有很好的金矿成矿条件,找矿潜力巨大,有存在大型金矿床的可能,应该加强该成矿带的找矿工作力度.
Guocheng fault,as a secondary ore-conducting fault of Tan-Lu fault,controls the distribution and out-put of gold ores in the area. And these gold deposits are also controlled by the interstratified glide fault on the edge of Jiaolai basin. The genesis of the gold deposits is marked by unique geological background and tectonics. The paper e-laborates the prospecting potential and prospecting direction of the gold deposits in Guocheng fault zone based on re-gional metallogenic background and deposit characteristics. The results suggest that there are large ore-bearing rocks and great potential for large-scale gold deposits. Exploration work in this region should be intensified.
