摘要:赣东北地区成矿地质条件优越，形成有德兴、银山、乐华等大型矿田；其中，银山多金属矿田可分为两个成矿系列6个矿床。本文在实地考察和室内研究的基础上，从地层、岩性、构造、岩浆活动、矿体地质特征等分析入手，结合同位素测试、包裹体分析等手段，对银山多金属矿田的成矿地质特征及矿床成因进行了探讨，认为区内成矿物质主要来源于岩浆分异及热液作用，古老地层提供了部分成矿物质；成矿作用具有多期、多次、多成因特征，是典型的多位一体矿田。

Abstract:The metallogenic geological condition was superiority in northeastern Jiangxi, where there were formed some large ore fields such as Dexing, Yinshan, Lehua, etc. Yinshan polymetallic ore field can be divided into two metallogenic series and consists of six deposits. Based on the detailed field investigations and comprehensive study, started with the analysis to stratum, lithology, construct, magmatic activity, ore body geological characteristics. Combined the isotope testing with inclusions geochemistry, The authors studied on the metallogenic geological characteristics and the origin of Yinshan polymetallic ore field, regarded that metallogenic material mainly derived from magmatic differentiation and hydrothermal activity, the ancient strata just provides part of metallogenic material. The metallogenic process had the characteristics of multi-phase, multi-stage and multi-genetic, and had typical multi-position and one-body features.
