Abstract:

The Huachanggou gold deposit is located in the south of the Qinling Mountain fold system，4 km north of Kangxian-Lueyang-Mianxian deep fault.The gold mineralization zone is controlled strictly by strata，lithology and ductile shear zone.Altered spilite and the transition parts between limestone and silty phyllite are the main ore-controlling strata.Compression shear fracture is the main ore-controlling structure.The gold orebody is occurred as veins and lenticle.Altered spilite and altered carbonatite are the main mineralized types.Pyrite is the main gold-carrying mineral.Occurrence of natural gold in the ore is observed included-gold and fissure-filled gold，the secondary type is intergranular gold.Wall-rock alternation are mainly pyrite，silicification，carbonatization，albitization，sericitization，etc.By studying the pyroelectric coefficient and primary halo of pyrite studies，the result shows that the gold ore body is extending to the deep part.It is advisable to strengthen the work of geological prospecting and ore exploitation between spilite ore belt and sandstone ore belt.

Key words: geological characteristics, ductile shear zone, metallogenic regularity, Huachanggou gold deposit, Shaanxi Province
