| 摘 要： | 产在潜火山岩中的七宝山金矿是中国与火山隐爆作用有关的比较典型的金矿床。金矿床严格受火山机构控制，中生代的火山喷发作用在七宝山地区形成破火山口，并形成了一组火山岩及潜火山岩。通过对该区火山岩、潜火山岩以及金矿床的研究，证实七宝山地区中生代的火山活动与金矿化密切相关。

| Abstract: | The Qibaoshan area locates in the southwestern part of the Jiaoliao depressi on,close to the Yishu fault system. There are many types of volcanic and subvoca nic rocks around the area, Mount Qibao is an ancient volcanic dome and the gold deposit in a cryptoecplosion breccia pipe. By means of studying the charact eristics of the ore deposit the gold mineralization is related to the volcanism. |
