摘　　要：白牛厂矿床是一个以银、铅、锌、锡、铜为主要成矿元素的大型超大型多金属矿床。其主要控矿因素为构造、沉积建造和岩浆活动。中寒武统田蓬组碎屑岩是最主要的赋矿地层;圆宝山复式向斜和F3断裂控制了多金属矿体的产出部位与形态;燕山期岩浆活动为矿床形成提供了重要物质来源、流体及热源,为围岩中成矿物质的活化、迁移和富集创造了条件。Bainiuchang deposit is a large-sperlarge Ag-Pb-Zn-Sn-Cu poly-metal deposit. Its main ore-controlling factors are structure?sedimentary formation and magma activity. The most important ore-hosting bed is detrital rocks in the Middle-Cambrian Tianpeng formation. Yuanbaoshan synclinorium and F_(3) controll the location and shape of ore-bodies. The Yanshanian magma activity provides the important ore element?fluid and heat for the formation of the deposit, and create the condition for the activation?mobilization and enrichment of ore-elements in host-rocks.
