西天山中、上元古界包括蓟县系库松木切克群和青白口系开尔塔斯群，为一套海相碳酸盐岩夹少量细碎屑岩和泥质岩，并有多层钾长岩、硅质岩和透辉岩等热水沉积岩，其沉积相为浅水碳酸盐台地相．上述地层为本区含矿地层，不仅其成矿元素含量高，而且产有热水沉积型和以矽卡岩型为主的复合型两类层控铜多金属矿床。地层对本区铜矿化有明显控制作用 In the Western Tianshan, the Upper Proterozoic includes the Quxian system kusongmczecun and the Qingbaikou kelitas group, which are a set of marine carbonate rocks with a small amount of fine clastic rock and argillaceous rock and multi-layer K-feldspathic, chert, diopside and other hydrothermal sedimentary rocks, the sedimentary facies are shallow-water carbonate platform. The above-mentioned strata are ore-bearing strata in this area. They not only have high metallogenic element content, but also have two types of layered copper-polymetallic deposits characterized by hydrothermal sedimentary type and skarn type. Strata on the area of ​​copper mineralization has obvious control
