位于中亚造山带北山褶皱带的甘肃黑山铜镍矿床是国内首例证实为在洋壳俯冲过程中形成的铜镍硫化物矿床(Xie et al.,2012)。以国内标准划分,黑山铜镍硫化物矿床Ni储量达到大型,Cu储量小型,平均品位:Ni 0.6%、Cu 0.27%,其中以1号和4号矿体规模最大。我们通过锆石U-Pb年龄(~357Ma),以及具有MORB和岛弧双重特征的微量元素、Sr-Nd-Pb同位素和单斜辉石的研究表明黑山含矿 The Gansu Montenegro copper-nickel deposit, located in the North Mountain fold belt of the Central Asian orogenic belt, was the first copper-nickel sulfide deposit confirmed to be formed during the subduction of the oceanic crust (Xie et al., 2012). According to the domestic standard, the reserves of Ni in the Montenegro copper-nickel-sulphide deposit reach a large size with small Cu reserves. The average grade is Ni 0.6% and Cu 0.27%, of which No. 1 and No. 4 ore bodies are the largest. Our study of Sr-Nd-Pb isotopic and clinopyroxenes by the zircon U-Pb age (~ 357Ma) and the trace elements with dual MORB and island arc characteristics indicates that the Montenegro ore-bearing
