摘　　要：本文在分析乌托沟银铅锌矿床区域地质、矿区地质和矿床地质的基础上,探讨其矿床成因及成矿特征。结果表明:区内受昆中深大断裂影响,强烈的构造活动为银铅锌的活化、迁移、富集提供了有利条件。乌托沟断裂是矿区控矿构造,其次级断层控制的破碎蚀变带和构造裂隙是矿区主要的储矿构造。乌托沟矿床是受构造控制的浅成低温热液脉型银铅锌矿。Based on the analysis of regional geology, mining area geology and deposit geology of Wutuogou silver lead zinc deposit, the genesis of the deposit is explored and its metallogenic characteristics is analyzed. The results are as follows: Affected by the Kunzhong deep faults, the strong tectonic activity in the area provides favorable conditions for the activation, migration and enrichment of silver, lead and zinc. Wutuogou fault is an ore-controlling structure in the mining area, and the fracture alteration zone controlled by the secondary fault and the structural fissure are the main ore-storing structures. Wutuogou deposit is an epithermal vein type silver lead zinc deposit controlled by structure.
