吉林省延边地区北部有大、中型原生金(铜)矿床和砂金矿床计五处,小型原生金矿床和砂金矿床十多处。本区探明的金矿储量约占全省金矿总储量的35％。综合研究认为:该区金矿与区内华力西晚期侵入杂岩和燕山期火山岩(包括次火山岩)在空间上与成因上存在密切联系。因此,研究本区侵入杂岩和火山岩特征,并探讨其与金矿床成矿的专属性,对指导本区寻找金矿床有着重要的现实意义。
There are five large and medium-sized native gold (copper) deposits and placer gold deposits in the northern part of Yanbian area in Jilin Province, more than 10 small gold deposits and gold deposits. The proven gold reserves in this area account for about 35% of the total gold reserves in the province. The comprehensive study shows that the gold deposits in the area are closely related with the genesis in the late Waringian intrusive complex and Yanshanian volcanic rocks (including sub-volcanic rocks). Therefore, studying the characteristics of intrusive complexes and volcanic rocks in this area, and discussing their specialization with gold deposits, is of great practical significance in guiding the search for gold deposits in this area.
