摘　　要：青龙沟金矿床已发现多处金矿(化)点,其矿床规模和资源储量具有一定规模。以青龙沟矿区地质特征为背景,得出,变质作用是金成矿作用的重要因素之一,变质作用对区内金乃至多金属成矿具有重要的意义;分析了矿床地质特征,区内先后发现了3个金矿带,分别为青龙沟金矿Ⅰ矿带、Ⅱ矿带及Ⅲ矿带;研究了控矿因素和矿床成因,控矿因素主要为地层、构造、岩浆活动和变质作用;矿床成因主要与构造和闪长岩脉关系较为密切。Many gold deposits(chemical)have been discovered in Qinglonggou gold deposit,and its deposit size and resource reserves have a certain scale.Based on geological characteristics of Qinglonggou Mining Area,this paper concludes that metamorphism is one of the important factors of gold mineralization,and metamorphism is of great significance to the formation of gold and even polymetallic mineralization in the area.The geological characteristics of deposit are analyzed.Three gold ore belts were discovered,namely Qinglonggou Gold MineⅠore belt,Ⅱore belt andⅢore belt.The ore-controlling factors and genesis of ore deposit are studied.The ore-controlling factors are mainly strata,structure,magmatic activity and metamorphism.The genesis of the deposit is closely related to structure and diorite veins.
