| 摘 要： | 摘要本文介绍了含有普通Os的铜镍硫化物的Re-Os同位素定年方法及其在新疆黄山东和金川铜镍矿床的应用实例。样品采用Carius管溶解，Re采取丙酮萃取、阳离子树脂交换分离，Os则采取蒸馏分离方式，质谱测量为电感辆合等离子体质谱(ICP-MS)。结果表明，采用ICP-MS进行铜镍硫化物的Re-Os同位素定年研究，同样能得到令人满意的结果。

| Abstract: | A method for Re-Os dating of copper-nickel sulfide ores and its application in the Huangshandong Cu-Ni deposit in Xinjiang and the Jinchuan Cu-Ni deposit in Cransu are presented in this paper. The technique of Carius tube was used to dissolve the samples. Rhenium was separated by cation exchange after acetone extraction and osmium by distillation. The results of the application show that ICP-MS can be used for Re-Os dating of copper-nickel sulfide ores with satisfactory results obtained. |
