摘　　要：燕山地区位于华北地台的北缘,是燕辽金成矿带的重要组成部分。金矿床主要分布在区域深大断裂带两侧的次级断裂构造中,太古界基底变质岩系和中元古界古长城、蓟县系沉积盖层是最早的初始矿源层,岩浆活动与金矿床成因关系密切,特别是燕山旋回中酸性岩侵入体,金丰度值高,变异性系数大,为金矿的形成提供了必要的物质条件。Yanshan region is an important component of Yan-Liao metallogenic belt located in the northern margin of North China platform. Gold deposits are mainly distributed in the sub-fauh tetonic of both sides of regional deep fault zone. The earliest initial ore source layers are Archean basement metamorphic rock series and Meso-proterozoic sedimentary cover of Changcheng and Jixian system. Magmatic activity is closely related with genesis of gold deposit, especially the acid rock intrusion of Yanshan cycle, highly abundance value and large variability coefficient provide necessary material conditions for the formation of gold.
