| Abstract: | The Huangshan ductile shear zone is a part of the Shaoxing-Jiangshan fault zone with features of a heterogenous and simple structural strain field. The shear slide sense is of oblique- orientation and thrusting nature with the total displacement of 40km. The gold mineralization is located in quartz veins in mylonite in the middle part of the shear zone (not in the most intense part of shear strain).The genesis of the deposit is considered to be migmatization- anatexis hydrothermal. The dynamic differentiation caused by shear-tectonic movement is possibly one of the factors for metallogenesis. Identifying ductile shear zone, superimposition sectors of altered zone and pyrite-concentrated zone on old metamorphic rock series and mylonites in fault zones are important prospecting guides for gold deposits. |
