摘　　要：猪拱塘铅锌矿床是黔西北地区近年新发现的超大型铅锌矿床。通过详细论述猪拱塘铅锌矿床找矿工作中的新发现,进一步分析该矿床的控矿特征及找矿潜力。结果表明:猪拱塘铅锌矿床的矿体在走向及倾向上均具有较好的延伸,且在F_(1)断层下盘栖霞组、摆佐组及F_(3)断层上盘摆佐组中发现了新矿体,提交铅锌金属资源量327.44万t,实现了黔西北铅锌矿找矿的重大突破。矿区具有构造、地层(岩性)、围岩蚀变、岩浆活动及物化探异常等重要找矿标志,成矿地质条件较好,具有寻找更多隐伏铅锌矿体的潜力。研究可为黔西北铅锌矿集区的找矿工作提供参考。As the newly discovered super large lead-zinc deposit in Northwestern Guizhou,the ore-controlling characteristics and prospecting potential of Zhugongtang lead-zinc deposit were analyzed through detail description of new discoveries in Zhugongtang lead-zinc deposit.The results show that the ore bodies of Zhugongtang lead-zinc deposit have a good extension in direction and tendency,and new ore bodies were discovered in Qixia Formation and Baizuo Formation of F_(1)footwall,and Baizuo Formation of F_(3)top wall.And 3274400 t lead-zinc metal resources were submitted,indicating a breakthrough in prospecting for lead-zinc deposits in Northwestern Guizhou Province.The mining area has important prospecting indicators such as structure,stratigraphy(lithology),wall rock alteration,magmatic activity,and geophysical and geochemical prospecting anomalies,and it also has good metallogenic geological conditions and potential to find more concealed lead-zinc ore bodies.This work can provide reference for the prospecting of lead-zinc ore accumulation in Northwestern Guizhou.
