| 摘 要： | 热液蚀变矿物，流体包裹体，脉石英，水热锆石和某些矿石矿物同位素定年方法的新进展使金矿床定年精度大大提高。热释发光等新技术区分成矿前或成矿后脉岩，异常铅模型研究可有效地示踪金矿化历史，在坚实的成矿背景和矿床地质地球化学基础上，采用多元同素体系结构分析是今后矿床定年的主要方向。

| Abstract: | Age determination precision of gold deposits has greatly improved with the newly progresses of isotope age determination of hydrothermal alteration minerals, fluid inclusion, vein quartz, hydrothermal zircon and some ore ninerals. Heat releasing luminescence can be used to distinguish pre-mineralization or post-mineralization vein rocks. And the research of anomalous lead model can effectively trace the history of gold mineralization. On the basis of ore-forming geological setting and geological and geochemical research of ore deposits, the synthetic analysis of multi-isotope system is the main direction of age determination method of gold deposits in future. |
