摘　　要：猪拱塘铅锌矿床位于川滇黔铅锌多金属成矿域东侧,是川滇黔地区首次在中二叠统栖霞组碳酸盐岩中发现的隐伏超大型MVT型铅锌矿床。笔者历时8年(2013—2020年)的勘查实践,在对猪拱塘地区成矿地质背景、矿床特征和构造控矿特征分析研究的基础上,认为猪拱塘铅锌矿床受紫云—垭都逆冲滑脱构造系统控制,受断裂构造控制是其基本特征之一。通过系统勘探,发现隐伏大型富厚铅锌矿体,提交铅锌资源量327.44×10^4 t,实现了贵州省铅锌找矿历史的最大突破。其矿床的勘查实践过程对区域内铅锌地质找矿具有重要指导及借鉴意见。The Zhugongtang lead-zinc deposit is located in the eastern part of the Sichuang-Yunnan-Guizhou Pb-Zn polymetallic metallogenic region. It is the first concealed super-large MVT lead-zinc deposit discovered in carbonate rocks of the Middle Permian Qixia Formation in the area after eight years of exploration(2013-2020). Based on the analysis of the metallogenic geological background, characteristics of the deposit, and the structural ore-controlling characteristics of the Zhugongtang area, we have believed that the Zhugongtang lead-zinc deposit was controlled by the Ziyun-Yadu thrust detachment structural system. The fracture-controlling is one of its basic characteristics. Through the systematic exploration, we have discovered the large sized concealed lead-zinc orebody with the lead-zinc resource of 3274400 tons, and have achieved the biggest breakthrough in the history of lead-zinc prospecting in Guizhou Province. The exploration practice of the Zhugongtang lead-zinc deposit has important guidance and reference values for prospecting lead-zinc resources in the northwestern Guizhou.
