| 摘 要： | 四川宁南县银厂沟-骑骡沟铅锌矿床产于震旦系上统灯影组白云岩中，主要受断裂控制。矿体多为透镜体状、网脉状和细脉状。与成矿有密切关系的硅质条带为富硅热液后期充填产物，显示后期热液充填成矿特点。分析研究认为该矿床在成矿的大地构造背景和其它特点方面，均与美国中部密西西比河谷型（MVT型）铅锌矿有相似性。

| Abstract: | The Yinchanggou-Qiluogou Pb-Zn deposit is confined to the dolomite of the Upper Sinian Dengying Formation. Most of orebodies are controlled by faults and occur as lens, vein network and veinlet. Siliceous bandings and jasper which are closely related to the mineralization are hydrothermal filler. Geological setting and mineralization features indicate that the deposit belongs to MVT Pb-Zn deposit. |
