CHARACTERISTICS OF ORE AND OCCURRENCE OF GOLD OF THE WANGJIAWAIZI GOLD DEPOSIT IN LIAONING PROVINCE, CHINA

The Wangjiawaizi gold deposit is situated in the southeast of Yingkou City, Liaoning Province. The ore of the gold deposit is dominated by gold-bearing quartz vein type, with rich pyrite as main gold-carrier. The pyrite, closely related to gold mineralization in time, space and genesis, is the significant indicator for the metallogenesis of gold. The ore is in heterogranular and metasomatic dissolution textures and massive, dense massive and veinlet-disseminated structures. The gold minerals are medium-to fine-grained electrum and goldargentid in complicated shapes, occurring in fissures, crystal cracks and inclusions. The gold-carrying minerals include pyrite, galena, sphalerite, chalcopyrite and quartz. The deposit is characterized by metamorphic hydrothermal type. The multi-sourced mesothermal and meso-epithermal fluid is the major ore-forming factor.
