| 摘 要： | 冀北东段是燕辽成矿带中有成矿远景的地区,不仅对铀成矿有利,同时又是金、多金属成矿的有利地区。工作区地处华北地台北缘东段,位于中生代构造活动带的边缘及多期构造活动带的叠加部位,形成各具特色的双层构造层,且有多期构造岩浆活动,形成有利的矿源层(体)。这些多期热改造事件,使成矿元素具备活化富集的条件。本文在分析区域地质背景及成矿条件的基础上提出3条成矿带及一片成矿有利远景区,并提出金成矿规律及找矿方向。

| Abstract: | The eastern part of northern Hebei is an area with metallogentic prospect in the Yan-Liao metallogenetic belt which is favourable not only for uranium metallogenesis but also for gold and polymetallic metallogenesis. The study area is located in the eastern part of the north margin of North China Platform and at the margin of the Mesozoic tectonically active zonc,and the superimposition part of multiphase tectonic active zones ,resulting in character-istic two-layer structure and multiple structural magmatic activities,and favourable ore-source beds (bodies).These multiple thermal reworking events led to the reactivation and concentration of ore-farming elements. By analyzing the regional geological setting and met-allogenetic conditions,this paper proposes three metallogenetic belts and a metallogenetically prospective area,and the metallogenetic regularity and prospective direction of gold are indi-Gated as weal. |
