Abstract:Now, more and more gold deposits occouring in ductile shear zone have been found in the world. According to the relation ship between main ore-foming stage and ductile shear zone, gold deposits are classified into synductile shear type and gold deposit of post ductile shear type. The main ore-foming stage of the gold deposits of synductile shear type is syn-chronous with the happening and formation of gold -bearing ductile shear zone. The ductile shearing activity not only provides places for ore deposits, but also is related directly with metallogenesis. the host wall rocks are ultramy-lonite, mylonite and protomylonite etc. Ore body is outlined by chemical analysis and the ores is mainly of disseminated type. The ore-foming stage of the gold deposits of post ductile shear type is obviously later than ductile shear deformation with a large interval. The type of ores is controlled by deformation charac-teristics of ore-bearing zone.
