华北地台北缘中段金矿成矿规律浅析及找矿方向

GOLD METALLOGENIC REGULARITY AND EXPLORATION DIRECTION IN MIDDLE SECTOR OF NORTH MARGIN OF NORTH CHINA PLATFORM

华北地台北缘地质环境复杂，金矿类型繁多，金矿空间分布不均一。对区内九处大型以上矿床的区域成矿地质背景、金矿成矿条件、控矿因素、成矿作用、矿床成因等进行对比和研究，认为区内的金矿床均属地层建造、构造、岩浆活动“三位一体”成矿；矿床成因类型有别，是成矿地质背景差异所造成的不同单元中的地层建造、构造运动、岩浆活动三个互补因素各自所起的作用不同所致；总结出不同类型金矿床的成矿规律。

In the north margin of North China Platform,the geological envirment is complex and gold deposits are various and space distribution of gold deposit is inhomogeneous.By comparing and studying regional metallogenic geological settings,metallogenic conditions,ore control factors,mineralizing processes and ore geneses of more than large scale of nine gold deposits in this area,gold deposits in this region have been considered to have the “three in one ”metallogenic feature of stratigraphic formation,structure and magmatic activity.Because of different agency of 3 associated elements,stratigraphic formation,tectonic movement and magmatic activity in different units caused by different geological settings,the genetic types of the deposits are different. The metallogenic regularities of different gold deposits are summerized.The exploration direction and target are ponited out.
