茂租铅锌矿位于扬子地块西南缘茂租断层和莲峰―巧家断裂交汇的三角带,是川滇黔铅锌多金属成矿域滇东北铅锌矿化集中区重要的铅锌矿床。矿区有上、下2个矿层,9个似层状矿体、2个脉状矿体。似层状矿体赋存于上震旦统灯影组白云岩中,顺层产出,矿体产状与地层产状一致；脉状矿体产于断裂破碎带中,矿体产状受断层控制。研究认为赋矿地层岩性、矿体围岩性质、矿区褶皱构造、区域性茂租断层的多次活动及其派生出的次一级 NE 向断层是区内铅锌矿形成的重要控制因素。根据成矿条件分析及化探异常显示,矿区南部深部及外围铅锌矿有较大找矿潜力。

Maozu Pb-Zn deposit,lying in the triangle intersection zone of Maozu fault and Lianfeng-Qiaojia fault at the southwest rim of Yangtze Block,is an important Pb-Zn deposit in northeast Yunnan Pb-Zn ore-concentrated area of Sichuan-Yunnan-Guizhou Pb-Zn polymetal metallogenic domain.The mining area con-sists of 2 ore-beds (upper one and lower one),hosting 9 stratoid orebodies,and 2 vein orebodies.The stra-toid orebodies occur in dolomite of Upper Sinian Dengying Formation along the direction of the strata while the occurrence of the orebody is same as that of the strata.The vein orebodies occur in faulted fracture zone, the occurrence of which is controlled by faults.For the formation of Pb-Zn deposit,the study suggests that the key controlling factors in this area include lithology of ore-bearing strata,wall rock properties of orebod-ies,fold structure,regional multiple activities of Maozu fault and the secondary NE-trending faults derived from it.According to the analysis on metallogenic conditions and geochemical anomalies,the deep part in the south part of the mining area and its peripheral area had great prospecting potential for lead and zinc prospec-ting.
