雪岭矿区铜多金属矿化沿灯影组和渔户村组层间断裂带产出，部分与辉绿岩接触产出。为了探索其成矿作用和成矿物质来源，在矿区系统取样，研究地层及辉绿岩地球化学特征。结果表明：矿区各地层均较上地壳富集 Ag、As、Pb、Sb，断裂构造运动有利于成矿物质的迁移富集。矿区辉绿岩为钙碱性系列岩石，形成于大陆板内构造环境，为峨眉山玄武岩同期产生的同源异相岩浆活动产物。经综合分析，矿区矿化应是深部成矿物质受构造运动活化运移至浅部构造有利位置沉淀富集所致，围岩提供了部分成矿物质，辉绿岩对矿化具一定积极的作用。

Cu-polymetallic mineralization occurs in the interlaminar fault of Dengying Formation and Yuhucun Formation in Xueling mining area, and parts of mineralization contact with diabase. In order to explore the mineralization and ore-forming material source, the systematic sampling was carried out to research the geochemistry characteristics of the strata and the diabase. The results show that the strata contain more element contents of Ag, As, Pb and Sb comparing with the upper crust, and the tectonic movement is beneficial to the migration and enrichment of metallogenic material. The diabase which formed in the tectonic settings for continental intraplate belongs to calc-alkaline series, it is the product of polymorphism magmatic activities of the Emeishan basalt. By synthetic analysis, the mineralization is resulted from that the deep metallogenic material activated and migrated under the influence of fault, then enriched in the shallow structural favorable position. The surrounding rocks provide parts of the metallogenic material, and the diabase is favorable for mineralization.
