摘要
铅锌矿体赋存于下寒武统筇竹寺组八道湾段(∈1q1)灰黑色中厚层状泥质粉砂岩中;筇竹寺组玉案山段(∈1q2)灰黄色、灰黑色泥质页岩夹薄层状细砂岩为矿区成矿的隔挡层。北东向的关仓箐逆断裂为矿区的导矿构造,北西西向次级张扭性断裂和北北东向层间断裂为矿区的容矿构造。
The Pb -Zn ore bodies in orefield exist in Lower Cambrian Qiongzhusi Formation Badaowan Member （∈1q^2 ） gray - black middle thick bedded argillaceous siltstone. The cut off layer of metallogenesis in orefield is Qiongzhusi Formation Yuanshan Member （ ∈1q^2 ） gray - yellow, gray -black argillaceous shale with intercalation of thin bedded fine sandstone. The Guancangjing NE reverse fault is the ore transmission structure in the orefield. The NWW subsidiary tension -torsion fault and NNE interlayer fault are the ore -bearing structure in the orefield.
