| 摘 要： | 长城型金矿分布于冀东地区冷口断裂带的北侧。成矿受冷口断裂带控制,产于中元古长城系、蓟县系白云岩中,沿冷口断裂带北侧成群分布。矿床的主要特征是金呈超微细浸染状,围岩蚀变非常微弱,矿石与围岩不好鉴别。矿床的一些特征与卡琳型金矿相似,是卡琳型金矿大家族中的一员。金矿呈气相迁移、沉淀成矿。

| Abstract: | The Changcheng type gold deposits distribute on the north part of the Lengkou fault zone in east of Hebei province.Mineralization is controlled by the Lengkou fault zone.The deposits developed in dolomite of proterozoic Changcheng and Jixian series and distribute in clusters along the north part of the Lengkou fault zone.The principal characteristic of the deposit is that the gold is ultra-fine disseminated with weak country rock alteration which makes it difficult to distinguish the ore and the country rock.The Changcheng type gold deposit belongs to the Karin type gold deposit family and some characteristics of it are similar to the Karin type.Gold was transported in a gaseous phase and then deposited. |
