| 摘 要： | 铅锌矿产于下白垩统景星组下段泥质粉砂岩、钙质砂岩和中侏罗统花开左组上段砂岩夹薄层泥灰岩介壳灰岩中，脉状、透镜状、层状、似层状等产出。NNE向断裂的交叉夹持部位的旁侧派生次级断裂及层间破碎带是主要容矿构造，矿床成因为沉积-中低温热液改造构造控矿型。

| Abstract: | This Pb -Zn deposit is in Lower Cretaceous Jingxing Formation argillaceous siltstone, calcic sandstone and Middle Jurassic Huakaizuo Formation Upper Member sandstone with intercalation of thin bedded marl and shell limestone, which is veined, lenticular, bedded and stratoid, etc. The main ore - bearing structures are the intersection of NNE faults, secondary fault beside it and the interstratified fracture. The genesis of ore deposit belongs to the type of sedimentation, middle -low T hydrothermal reformation and structure control. |
