位于西秦岭北带的丹凤群是一套浅—中等变质的绿片岩系，原岩为一套以基性—中酸性火山岩为主夹正常陆源碎屑岩、碳酸盐岩的岩石组合。该变质岩系分布区金的地球化学丰度高，断裂作用和岩浆活动十分强烈。丹凤群兼具基性—中酸性火山岩、印支—燕山期断裂构造及中酸性岩体“三位一体”成矿条件的地段是成金的有利部位 Danfeng Group, located in the northern part of the West Qinling Mountains, is a set of shallow metamorphic greenschist rocks. The original rock is a set of rock assemblages with normal terrigenous clastic rocks and carbonate rocks dominated by basic-acidic volcanic rocks. The geochemical distribution of gold in the metamorphic rocks is high in geochemical abundance, with strong fracture and magmatic activity. Danfeng group has both basic - acidic volcanic rocks, Indosinian - Yanshanian fault structure and intermediate-acidic rock “Trinity” metallogenic conditions of the lot is a favorable site for gold
