摘　　要：义盛店铀银多金属矿区位于西干沟大型破火山机构的北侧,铀银多金属矿主要产于次火山岩体内的隐爆角砾岩中及次火山岩体盖层中。文章介绍了义盛店次火山岩型铀银多金属矿床的地质特征,分别从矿体(层)赋存规律、成矿物质来源、控矿构造特征、成矿环境分析等方面对其矿床成因进行了探讨,总结了成矿模式。The Yishengdian uranium- silver polymetallic deposit is located in the north part of large- sized Xigangou volcanic Caldera structure. The uranium - silver polymetallic orebodies mainly occur in the cryptoexpolsive breccia and the sub - volcanic cov- er. This paper introduces the geological characteristics of Yishengdian uranium - silver polymetallic deposit in detail, the ore deposit genesis was discussed in aspects of occurrence regularities of orebody （layer） , ore - forming material sources, tectonic characteristics and metallogenic environment, and the metaUogenic model was summarized finally.
