摘　　要：新疆阿尔金翁库尔·萨依西铅锌矿是2015—2018年新发现的铅锌矿产资源基地。铅锌矿主要赋存于蓟县系金雁山组白云岩内,中薄层状—厚层状构造,具典型沉积岩层状构造特征,矿体与围岩呈渐变过渡关系。通过槽探工程揭露发现M1和M2两条铅锌矿体,M1矿体长1820 m,平均厚度37.97 m;锌平均品位6.45%。M2矿体长2742m,平均厚度7.11 m;锌平均品位5.35%。铅矿化不均匀,铅最高品位0.62%。对两矿体初步估算,推测铅锌潜在金属资源量279万吨,推测矿床规模为超大型。通过对该矿床成矿地质特征研究,总结找矿标志,认为1∶5万水系沉积物化探综合异常HS12-甲1内及外围同层位异常带具有较大的找矿潜力。在矿区加强地质-物化探-钻探综合找矿技术方法应用,有望实现较大的找矿突破。The West Wengkuer-Sayi lead-zinc deposit in the Altun area, Xinjiang is a newly discovered deposit from 2015 to 2018. The lead-zinc deposit is mainly located in the dolomite of Jinyanshan Formation of Jixian System. It has medium thin bedded to thick bedded structure with typical sedimentary rock stratum structure characteristics. There is a gradual transition relationship between the orebody and surrounding rock. Two lead-zinc orebodies, M1 and M2, are discovered through trench exploration. M1 orebody is 1820 m long and the average thickness is 37.97 m. Zn has an average grade of 6.45%. M2 orebody is 2742 m long with an average thickness of 7.11 m. Zn has an average grade of 5.35%. Lead mineralization is not uniform, and the highest grade of Pb is just 0.62%. According to the preliminary estimation of the two orebodies, the potential metal resources of lead and zinc are estimated to be 2.79 million tons, which is extremely up to the large scale. Based on the study of the metallogenic geological characteristics of the deposit, the paper summarizes the prospecting marks, and it is considered that there is a great prospecting potential for the inner and outer zones of the 1∶50 000 stream sediment geochemical comprehensive anomaly HS12-A1. By strengthening the comprehensive application of geological, geophysical and geochemical exploration methods and drilling technology in the mining area, it is expected to achieve a major prospecting breakthrough in the future.
