本文在概括易门铜矿区成矿地质背景及矿床地质特征的基础上 ,讨论了火山热水沉积作用、构造改造作用、岩浆叠加作用及地下热水再造作用与成矿的关系 ,认为易门式铜矿床为“裂谷成矿背景—火山热水沉积—构造改造富集—深源岩浆叠加—地下热水再造”型多因复成矿床 ,最终建立其成矿模式 ,为今后的找矿预测指明了找矿方向 This paper summarizes the metallogenic geological background and geological characteristics of the Yimen copper deposit, and discusses the relationship between volcanic hydrothermal sedimentation, tectonic remolding, magmatic superimposition and underground hot water recycling and mineralization. Type copper deposit is a multi-factor complex ore deposit with the background of “rift metallogenic background-volcanic hydrothermal sedimentation-tectonic enrichment-deep source magmatic superimposition-underground hot water recycling”, and finally establish its metallogenic model for the future Mine prediction indicates the prospecting direction
