METALLOGENESIS OF AURIFEROUS SHEAR ZONE TYPE OF GOLD DEPOSITS

Based on an integrated study and comparison of the shear zone type of gold deposits both in China and abroad, the authors sum up the conception and criterions of auriferous shear zone and gold deposits of the type. By examination of Paishanlou gold deposit in Fuxin, Liaoning Province, it is concluded that the auriferous ductile or ductile-brittle shear zone is the specific result during the forming stage of supracrustal rock and basement rock series or the metamorphic-deformation stage of syntectonic cycle. Therefore, it can be referred as to auriferous syn-ductile shear zone. Such shear zone is a structural style that can preserve auriferous fluid. The metallogenesis for shear zone necessarily undergoes the following process:uplifting to shallow level, convergence of ore-forming fluid and deposition of mineral elements. The variety of metallogenetic process results in different metallization types of gold deposits.
