摘　　要：东胜铅金矿产于NE向板石沟断裂中,赋矿围岩为大石桥组大理岩。矿床地质特征和矿床地球化学特征表明,矿床为岩浆热液产物,成矿物质部分来自于地层,成矿热液中有大气降水的渗入,成矿温度为205~286℃,成矿流体密度为0.95~1.02 g/cm3,成矿压力为40~55MPa。Dongsheng Pb-Au deposit occurs in Banshigou fracture trending in NE direction and is hosted in the marble of Dashiqiao formation. It is geologically and geochemically characterized by magma hydrolhermal ore deposit. Ore materials are partly derived from the strata and the ore-forming processes is incoporated with meteoric water. The ore is formed at 205~180℃, 40~55 MPa and the ore fluid density is (about) 0.95~1.02 g/cm^3.
