Abstract:

小佟家堡子金矿床位于辽东金矿集中区,为产于古元古代变质岩系中的微细粒浸染型金矿,矿床类型独特。文章采用了绢云母40Ar/39Ar法对样品从450℃到l400℃进行了8个阶段的加热分析。从绢云母石英交代岩型金矿石中挑选出与金矿化密切共生的绢云母单矿物通过40Ar/39Ar快中子活化阶段加热法获得坪年龄为167Ma。绢云母40Ar/39Ar法测年结果与矿床的控矿构造特征、区域岩浆活动的演化规律相吻合,进一步证明了该金矿床为燕山期成矿。同时绢云母40Ar/39Ar的马鞍形年龄谱还表明在绢云母石英交代岩形成过程中可捕获部分“过剩氩”这可能是造成K_Ar法年龄值高、范围较大的原因之一。
