夹皮沟金矿区是我国重要产金区之一,已有150余年的开采历史。已开采和探明的金矿床主要为一些赋存于古老变质杂岩中、含金和少量硫化物的石英脉。对于其成因,前人主要根据金矿床多沿花岗岩侵入体外接触带分布、矿脉与岩脉有密切的空间关系、岩体副矿物成分与金矿床的金属矿物有类似之处及某些侵入体含金量较高等,认为成矿作用与印支(或海西)期花岗岩有关,属岩浆期后中温热液裂隙充填型矿床。
Jiapigou gold mining area is one of China’s major gold-producing areas, has more than 150 years of mining history. The gold mines that have been mined and proven are mainly quartz veins, which contain gold and a few sulfides in ancient metamorphic complexes. For its causes, the predecessors are mainly distributed along the in-vitro contact zone of granite in accordance with the gold deposits. The veins and dikes are closely related to each other. The accessory mineral composition of the rock body is similar to the metallic mineral of the gold deposit and the gold content of some intrusions It is considered that the mineralization is related to the Indosinian (or Hercynian) granite, and is a mid-temperature hydrothermal fissure-filling deposit after the magmatic period.
