河北隆化县金银铅锌矿产分布规律及找矿前景初探

Preliminary study on the spatial distribution rules of gold, silver, lead and zinc deposits and prospecting potential in Longhua area, Hebei

隆化县地处华北地台北缘中段,地层发育,构造活动期次多,岩浆岩活动强烈,各类矿产丰富,属承德地区有色金属矿产成矿聚集区之一。其中金、银、铅、锌等矿产在空间、时间分布和矿物组合等方面,有明显的规律性。但迄今为止,未能形成大的矿产地。文章根据该区成矿条件,筛选了部分成矿有利地段,可作为下一步找矿工作的重点。

Longhua mineralization area is located in the middle section of the northern margin of the North China Platform, where the ore - bearing strata is well developed and multi - stages of tectonic and magmatic activities occur, and various of mineral resources are abundant, Longhua area is one of the most important mineralization fields of nonferrous metals in Chengde region. There are apparent spatial -temporal distribution patterns of Au, Ag, Pb and Zn mineralizationas well as mineral assemblages. However, there is no any significant mineral deposit field discovered yet. According to the study on metallogenetic conditions, the author selects some favorable targets which could be explored in the next stage of prospecting work.
