摘　　要：青海省矿产资源丰富,矿种繁多。其中柴北缘是重要的铅锌金等矿产地。而在柴北缘地区的中西部还分布着锡铁山大型的铅银矿产区和双口山铅银矿产区。前人只是重点对柴北地区的锡铁山的铅金矿进行了重点的研究,而对双口山的矿产资源并没有深入的研究,所以很多人对双口山的了解比较薄弱。我们通过对矿产区内的地层、构造及矿体特征等进行了全面的分析,得出双口山的铅银矿产是在华力西时期形成的,双口山铅银矿源层是滩间山火山岩,双口山的北西南东方向的断裂构造对矿地层的分布有影响。Qinghai Province is rich in mineral resources and has many kinds of minerals. The northern margin of Qaidam Basin is an important mineral area such as lead, zinc and gold. In the central and western part of the northern margin of Qaidam, there are also large-scale lead-silver mineral areas in Xitieshan and Shuangkoushan lead-silver mineral areas. The predecessors only focused on the Xitieshan lead-gold deposit in northern Qaidam, but did not study the mineral resources of Shuangkoushan in depth, so many people have a weak understanding of Shuangkoushan. Through a comprehensive analysis of the strata, structures and ore body characteristics in the mining area, it is concluded that the Shuangkoushan lead-silver deposit was formed in the Warwick Period, the source bed of the Shuangkoushan lead-silver deposit is intertidal volcanic rocks, and the NE-NW trending fault structure of Shuangkoushan has an impact on the distribution of the ore strata.
