Jingshan superlarge gold deposit is a typical deposit closely related to the ductile shear zone, developing the economic enrichment during the transition form the ductile deformation to the brittle deformation. The oreforming process of Jingshan Au deposit can be described as the development of marine volcanicturbidity current Aubearing initial sedimentation→regional metamorphism and the first enrichment→strong transformation of dynamic metamorphism and deformation→orecontrolling and oreholding of ductile shear structure→supperimposed transformation and enrichment of magmahydrothermal solution. This process can be summarized as the “sourcemigrationaccumulation” metallogenicgeochemical process of Au. The proved Au reserve of this deposit has ex ceeded 100 t and its prospect of searching for ore is considerable. So it is called the only superlarge gold deposit in the south of the lower reach of the Yangtze River, China.
