摘　　要：本文以夹皮沟、辽宁、冀东、张家口、小秦岭、胶东、湘西、粤西─海南、三江、北疆和台湾等重要金矿比集中区为例，讨论了我国不同地区某些典型金矿床的成矿年龄，并在此基础上概括了我国不同地质时期金矿床的分布特征、矿床类型和成矿环境。在金矿成矿历史上存在一老（晚太古代─早元古代）一新（中新生代）两个成矿高峰时期，前者以形成绿岩建造金矿床为特征，后者则以发育花岗岩建造金矿床为特征。“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。The mineralizing ages of some typical gold deposits were discussed in Jiapigou，Liaon-ing， Eastern Hebei Zhangjiakou，Xiaoqinling，Jiaodong，Western Hunan，Western Guangdong－Hainan， Western Yunnan， Northern Xinjiang and Taiwan gold ore concentrated fields andso on. On the basis of this，the features of distributions，types and genesis of gold deopsitsat various geologic periods were summarized． During the evolutionory history of gold miner-alization，Late－Archeozoic or Early－Proterozoic Era and Mesozoic－Cenozoic Era are thetwo most important periods，the former is characterized by the greenstone formation type ofgold deposits， but the latter is characterized by granite formation type of gold deposits． Themost striking features of gold deposits in China are older ages of source of metallogenic mate-rial and younger fixed ages of deposits， that is ， gold mineralization shows the distinct inheri-rance.
