(1) The formation and evolution of the structural system of ductile-britlle shearing deformation and metamorphism is a key to the high enrichmant of gold in the Jinshan region. (2) The emplacemental mechanism of gold deposits is governed by the multi-level, accumulative and progressive mineralization in the structural system. (3) The epi-intrusion of granodiorite-porphyry makes a last contribution to the enrichment and mineralization of gold.
