摘　　要：多宝山铅锌矿床产于上白垩统铁隆滩群碳酸盐岩中,围岩蚀变主要有碳酸盐化、硅化、高岭土化、黄铁矿化,硅化、褐铁矿化灰岩的Pb、Zn、Ag、As含量极高,矿体明显受碳酸盐岩和构造破碎带控制。流体包裹体测温证实成矿具有盆地热卤水特征,多宝山铅锌矿具备典型的密西西比河谷型(MVT)铅锌矿成矿特征。Duo baoshan iron deposits are found in uppercretaceous long beach group of carbonate rocks, wall rock alterationincludes carbonatization, silicide, kaolin, pyritization, silicification,limonite limestone of high content of Pb, zinc,Ag,As, ore bodies controlled by carbonate rocks and tectonicfracture zone obviously. Fluid temperature cervix confirm metallogenicbasin hot brine characteristics, duo baoshan lead - zincmine has more typical of the Mississippi valley type （MVT） lead- zinc metallogenic features.
