| 摘 要： | 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

| Abstract: | The Danfeng Group located on the northern belt of West Qinling area is a series of epizonal-middle metamorphic greenschist and has high geochemical abundance of gold.In this belt faults and magmatism were strongly developed.We think that in the Danfeng Group the places where intermediate-acid-basic volcanic rocks,Yanshanian-Indosinian faults and intermediate-acid intrusions appeared together are the favorable minerogenic places for gold. |
