白音哈尔金矿床成矿作用

Abstract

Abstract:

The Baiyinhaer gold deposit is a typical gold—bearing qua~z veins type and gold—beating altered rock type omposite gold deposit in polymetallic ore belt of the northern margin of North China Craton．On the basis of high—reso—lution geological mapping，measurement and study of tectonics，analysis 0f geochemistry Of Au，As，Ag，Cu，Pb，Zn，Bind 0ther elements．We consider that the distribution of the ore—veins of the Baiyinhaer gold deposit is controlled by he fracture zones of the NE．NNE and EW strike．The mineralization of the Baiyinhaer gold deposit is a product of SU—
perposition of gold multi—stated mineralization．which is bound up with the intermediate—acid intrusive rocks in the area．The ore—forming materials of quaaz veins type of gold—bearing ore mainly come from the Group Rocks of the Middle nd Upper Proterozoic Erathem．while the 0re—forming materials of altered rock type of gold—bearing ore mainly come rom the qua~z—diorite and plagiogranite~rmed in late Variscan Age in the area．

Key words: Gold deposit, Altered rock, Source of ore-forming materials, Northern margin of Noah China Craton, Baiy&mdash, nhaer
