瓦勒根金矿床地处西秦岭，是在西秦岭成矿带青海省境内发现的唯一一处大型金矿床。通过分析瓦勒根矿区地质背景、矿床(体)特征、岩(矿)石化学成分及含量，认为金矿体主要产于早、中三叠世隆务河组的由碎屑岩、碳酸盐岩构成的沉积岩和中酸性侵入岩容矿岩石中，矿石由含金矿物呈浸染状分布在容矿岩石中构成，就位于断裂空间，严格限制在断裂破碎带中。金矿床的形成是构造运动、岩浆活动和沉积作用的综合产物，金矿床的形成受成矿物质来源、成矿环境和成矿作用3个要素共同制约。区域上与甘肃境内合作、夏河金矿化带相连，其成矿背景与枣子沟金矿、寨上金矿、大桥金矿、阳山金矿及南部玛曲南坪金成矿亚带的大水、忠曲金矿一致，矿床成因特征非常相似，同属微细粒浸染型金矿床。

The Walegengold deposit is located in western Qinling Mountains,is the only one large gold deposit found in Western Qinling metallogenic belt in Qinghai Province. By analyzing the ge-ological background,deposits (body)characteristics,rock (ore)chemical composition and its content of Walegen deposit,the results show that the ore bodies was mainly produced in sedimen-tary rocks (composed byclastic and carbonate rocks)and intermediate-acid intrusive rocksof Ear-ly and Middle Triassic Shilongwuhe Formation.The ores are formed by gold-bearing mineral, which were disseminated in the ore-bearing rocks,located and limited within the fracture zone. The formation of gold deposit is the integrated product of tectonic movement,magmatism and sedimentation,which is controlled by ore-forming material source,metallogenic environment and mineralization. Regionally,this deposit is connected with the Hezuo and Xiahe gold mineralized belts in Gansu Province,having the same mineralization background with Zaozigou,Zaishang, Daqiao,Yangshan gold deposits,as well as the Dashui and Zhongqu gold deposits in the Maqu-Nanping gold mineralized sub-zone. All of these gold deposits have similar genetical characters, belonging to the micro-grained disseminated gold deposit.
