-
摘要: 同位素稀释中子活化分析铼与感耦等离子体质谱法测定锇相结合，应用于辉钼矿及铜＿镍硫化物矿物的铼＿锇年龄测定，取得了满意的结果，扩大了铼＿锇测年法的应用范围。Abstract: A method for the determination of Re and Os by isotope dilution neutron activation analysis and ICP_MS is developed. The method has been applied to the molybdenite geochronology and copper_nickel sulfide isochron dating with satisfactory results.
