| 摘 要： | 本文汇集和讨论了夹皮沟、辽宁、冀东、张家口、小秦岭、胶东、湘西、粤西－海南、滇西、北疆和台湾等我国主要金矿化集中区某些典型矿床的成矿年龄．在此基础上讨论了金矿床蚀变矿物、流体包裹体、石英、水热锆石、裂变径迹和矿石矿物同位素年龄测定新方法及热释发光技术在金矿床定年中的进展。普通铅模式年龄的定年意义是很有限的，但异常铅模式研究可用来示踪金矿化历史。＂成矿物质来源年龄老，矿床定位年龄新＂，即成矿作用具有明显继承性是中国金矿床最突出的特征。

| Abstract: | The mineralizing ages of some typical gold deposits in China are collected and discussed.On the basis of this,the advancements in radiometric dating methods of hydrothemal altered minerals,fluid inclusion,vein quartz,hydrothermal zircon,some oreminerals and thermoluminscence technology are discussed.The importance of common lead model ages are very limited in the ditermination of minerogenetic epoches,but studies of anomalous lead models may be applied as an indicating tracer of the history of gold mineralization.The most striking features of gold deposits in China are older ages of source of metallogenic material and younger fixed ages of deposits,that is,gold mineralization shows the distinct inheritance. |
