Abstract：The Harigentai Ag-Zn-Cu polymetal deposit, located in the Western Daxinganling Pb-Zn-Ag polymetal metallogenic belt, is controlled by the secondary S-N-trending fault of the E-W-trending Mishengmiao anticlinorium. The ore/mineralized bodies, occuring in the structural fracture zones, are composed of quartz veinlets and networks in complex style. The mineral composition, structures and types of ore are studed. The results show that the mineralization is related to silicification, K-feldspathization and flouritization. The forming of the deposit is on intimate terms with the Jurassic granitic magmatism. The genesis of the deposit belongs to magmatic hydrothermal type.
