Abstract:

The ore-forming characteristics of Hulugou gold deposit was studied based on analyzing of its metallo-genic geology background and geology features.It is found that the orebodies of Hulugou gold deposit mainly occurred as the vein and lenses；Ore minerals are mainly pyrite and galena，chalcopyrite，sphalerite，gangue minerals are mainly potassium feldspar，quartz；Ore texture mainly are xenomorphic and hypidiomorphic，euhedral crystal and crushing structure，ore structure are dominated by massive and cataclastic structures；Wallrock alterations near the orebody are silicide，potassium，pyritization and silk lithification.Besides，through the analysis of characteristics of rare earth elements in mining area，the article comes to the conclusion that the material of Hulugou gold deposit is derived from Taihua Group，Archaeozoic erathem，which belongs to the occurrence in the old metamorphic rock of middle to low temperature quartz-vein type and fractured altered rock-type gold deposit.

Key words: geological characteristics, rare earth elements, Hulugou gold deposit, Shaanxi Province
