    矿化期同位素年龄测定的样品挑选及元素分离技术的研究

    STUDY ON SAMPLE SELECTION AND ELEMENT SEPARATION FOR ISOTOPIC DATING OF MINERALI ZATION

      摘要
    • 摘要: 本文以胶东等地同一矿化期不同阶段的金矿进行系统Rb-Sr法同位素年龄测定为例，确认矿化期同位素年龄测定中挑选合格样品必须满足下列条件：含有母体87Rb、子体87Sr；其中Rb、Sr的含量自地质体形成至今保持不增不减，即始终处于"封闭体系"。用同期金矿化不同矿化阶段的蚀变带岩石或矿物做等时线即可得到不同矿化阶段的年龄。在元素分离技术方面（Rb、Sr分离）：试样用氢氟酸和高氯酸分解后以盐酸提取，经200-400目强酸性阳离子交换树脂进行交换分离，后由质谱测定。

       

      Abstract: It is important to choose available samples and to separate elements for isotopic dating of mineralization in laboratory besides geological survey in field. But it has been paid less attention to and has led to produce some mistake results of tests and measurements in laboratory and is responsible for the confused knowledge on metallogenetic age.
