摘　　要：青海省赛什塘铜矿床位于都兰—鄂拉山三叠纪火山—岩浆弧及弧前增生楔东南端,矿床经历了多种成矿作用、具多种矿化表现形式,属于典型的复成因铜矿床。文章分析了层控改造型、矽卡岩型和斑岩型矿化的不同表现特征,探讨了三者之间的内在联系及其成矿过程,并在此基础上提出了三位一体新的成矿模式。Saishitang copper deposit is located in the Triassic volcanic - magmatie are and the southeast end of foreare accretionary wedge in Dulan - ela mountain. Saishitang copper deposit has a typical muhi - genesis, with kinds of mineralization pattern after experiencing series of mineralization. Based on the analyses of different characteristics and connection of stratabound mineralization, skarn mineralization and porphyry mineralization, this paper puts foreword a new trinity metallogenic model.
