礦區主要由東西向壓性斷層及與之伴生的近南北向張性斷裂、北東和北西向扭性斷層組成。區內褶皺構造主要有金廠峪復背斜及崔堡子復向斜，并伴有次一級小的背、向斜。金廠峪金礦床位于前述的復背斜軸部。
控礦構造以北北東向壓扭性斷裂最發育，表現形式為片巖帶或片理化帶。礦區內共有6條，片巖帶的形態和交匯部位往往是控制單個礦體的主要構造。
礦區含金復脈帶是由石英脈、鈉長石英脈、鈉長石脈、次生石英巖等斷續分布于片巖帶中。長1500m、寬460～900m，在本礦床6個復脈帶中共圈出大小16個工業礦體。礦體多集中于Ⅱ、Ⅲ、Ⅳ帶中。以Ⅱ2、Ⅲ3、Ⅳ4礦體最富，Ⅱ5規模最大。金礦平均品位10.6g/t。
The mine area is composed of the East and west of the East and the west, and the north and west to the East. In the fold structures are mainly Jinchangyu complex Baoziwan anticline and Cui Xiang Xie, and Xiang Xie, back with a secondary small. Jinchangyu Gold Deposit is located in the complex anticline.
The ore controlling structure of NNE trending compressoshear faults are most developed, form or schistositilization schist belt. In the mining area of a total of 6, the morphology and the intersection of schist belt is usually the main tectonic control single ore body.
Gold mining area complex vein zone is composed of quartz, albite quartz vein, sodium feldspar veins, secondary quartzite intermittent distribution in schist belt in. Long 1500m, width of 460 ~ 900m, in the 6 mineral deposits Fumai the circle size of 16 industrial orebody. The ore bodies are concentrated in the middle of the second, third and fourth. The ore bodies of 2, 3, 5 and 4 are the most abundant, and the second is the largest. Gold average grade 10.6g/t. |
