摘　　要：四川会东大梁子铅锌矿为MVT型铅锌矿床,产于NWW向F 1与F 15断裂所挟持的断陷构造带中;含矿围岩为寒武系、震旦系白云岩,NWW向断裂和NW向断裂的交汇部位是矿体的发育区段,富矿体多产于“黑色破碎带”的下侧;研究认为,矿床的成矿地质体为沟通会理群与下震旦统灯影组和下寒武统麦地坪组、处于碳酸盐岩与泥页岩转化部位的NWW向和NW向断裂交汇处的构造破碎带;文章还对矿床深部及外围的找矿潜力进行了预测。Daliangzi Pb-Zn deposit is a MVT type deposit occurring in a fault depression strucural belt held by NWW fault F 1 and F 15.The host rock is Sinian and Cambrian dolomite.Ore bodies are developed at intersection of NWW fault nd NW fault and rich ore in"the black clastic zone".The structurally clastic zone which penetrates Huili Group,Lower Sinian Dengying Formation and Lower Cambrian Maidiping Formation at intersection of NWW fault and NW fault in the transformational zone from carbonate rock to mud shale.The ore potential is made to depth and surroundings of the deposit.
