The Zhujiashan-Dachangan copper polymetallic metallogenic belt in the western part of North Qilian is an important copper-polymetallic metallogenic belt in North Qilian.The outcrop strata are Ordovician, volcanic rocks are well developed, copper mineralization and Copper and geochemical anomalies are very common.Jinuquan copper deposit, typical in the belt, is produced in the Ordovician basic volcanic rocks and tuffs and is fractured within the mining area with joint structure developed and can be divided into two ore belts in the east and the west. And the blind ore body 1 1, the genesis of the deposit belongs to volcanic jet (flow) sedimentary remodeling, the material comes from the upper mantle
