| 摘 要： | 墨江金厂是一个类型比较特殊的大型金矿床，与超基性蛇绿岩具有密切成因联系。其成岩成矿时代问题尚有不同认识，通过同位素年龄资料对比，认为金矿成矿母岩－蛇绿岩体是加里东晚期的产物；通过^40Ar-^39Ar法和其他方法的年龄测定以及野外对各类金矿化石英脉的对比研究，认为从海西至喜马拉雅期均有不同程度的金矿化。该矿床为多期次、多阶段叠加富集成矿。

| Abstract: | Jinchang gold deposit is a typical large scale deposit in Mojiang- it has close relation with ultrabasic ophiolite rock in genesis.The age of diagenetic and metallogenic is in different points. According to the comparison of isotope ages, the diagenetic mother rock (ophiolite rock) is the result of late Caledonian. The 40 Ar 39 Ar dating and other dating age and the comparison of varied quartz vein which had gold mineralization show that different degree gold mineralizations had taken place from Hercynian to Himalayan period. The gold deposit is a telescoped deposit as the result of multistage and polyperiod. |
