易门三家厂铜矿位于云南易门铜矿带西部 ,按产状、矿物组合及成矿作用可分为狮山式和凤山式矿床。矿床地质、地球化学研究结果表明 ,三家厂铜矿狮山式矿床是沉积岩容矿的海底喷流热水沉积硫化物矿床 ;凤山式矿床是狮山式矿床经后期构造和热液改造的产物。
Located in the west of Yimen copper deposit in Yunnan, Yimen Sanji Copper Mine can be divided into Shishan-type and Fengshan-type deposits according to occurrence, mineral assemblage and metallogenesis. The results of geology and geochemistry of the deposit show that the Shishan deposit in Sanjiachang Copper Mine is a submarine jet hydrothermal sedimentary sulphide deposit hosted by sedimentary rocks. Fengshan deposit is the product of the Shishan deposit through post-tectonic and hydrothermal alteration .
