摘　　要：白岩子锡、铅、锌多金属矿床主要赋存于二叠系下统大东厂组下段（P1dn1）地层中,矿体与南北向构造和岩浆岩关系密切,本文通过对云南腾冲白岩子锡、铅、锌多金属矿床的地质特征、岩浆活动、变质作用、围岩蚀变、成矿物质来源、控矿条件等多方面的分析和研究,认为白岩子锡、铅、锌多金属矿床属中～高温气成热液形成的锡石～多金属硫化物型矿床.Baiyanzi Sn-Pb-Zn muhimetallic deposit is mainly in Lower Permian Dadongchang Formation Lower Member （PidnI） , orebody is in close relation to NS structure and magmatic rock. In this paper, according to the analysis and study of geological feature, magmatism, metamorphism, alteration of wall rock, source of metalloge- netic material, ore control condition, etc, we think Baiyanzi Sn-Pb-Zn multimetallic deposit belongs to middle- high T pneumatolitic-hydrothermal cassiterite muhimetallic sulfide type deposit.
