Abstract: 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 ore-forming process of Jingshan Au deposit can be described as the development of marine volcanic-turbidity current Au-bearing initial sedimentation→regional metamorphism and the first enrichment→strong transformation of dynamic metamorphism and deformation→ore-controlling and ore-holding of ductile shear structure→supperimposed transformation and enrichment of magma-hydrothermal solution. This process can be summarized as the "source-migration-accumulation" metallogenicgeochemical process of Au. The proved Au reserve of this deposit has exceeded 100 t and its prospect of searching for ore is considerable. So it is called the only super-large gold deposit in the south of the lower reach of the Yangtze River, China.
