摘要
潼峪金矿区位于小秦岭金矿田西段,处于大月坪—金罗斑复式主背斜北翼,断裂构造为北东向、东西向及近南北向3组。含金构造带受控于这3组断裂构造,由石英脉及蚀变岩组成。矿脉分为陡倾斜和缓倾斜两类,缓倾斜矿脉具有等间距平行分布特征。通过坑道及钻孔工程控制,矿区中深部存在同类型缓倾斜富集矿段,结合控矿因素分析,在矿区中深部及边部,通过进一步地质找矿工作,有望发现新的大型金矿床。
The Tongyu gold deposit is located in the western part of the Qinling mountains gold ore field and northern part of Dayuping-Jinluoban complex domain anticline, the NE-, EW- and NS- trending faults are well developed in the deposit area. The gold-bearing structural belt consisting of quartz veins and altered rocks is controlled by these three groups of faults. The gold vein is divided into steep inclined vein and gentle inclined vein, and there is equidistant parallel distribution for the gentle inclined vein. By the verification of tunnelling and drilling engineering work, it was found there is enriched gentle inclined vein. In combination with orecontrolling analysis, it is predicated it is probably to find new gold orebodies in the middle and deep parts of the gold mine area in the next stage exploration.
