The ductile shear zone type gold deposit is one of important gold deposit types. Deep-level ductile shear deformation causes the element Au to be remobilized, forming Au-bearing tectono-metamorphic hydrothermal solutions, the medium- and shallow-level ductile-brittle deformation locus is the favorable site for gold accumulation. The types of gold mineralization are controlled by shear deformation levels and features of fault rocks. The important features of the ductile shear zone type of gold deposit are that mineralization occurs after the ductile shear deformational stage; gold orebodies mainly occur in some smaller ductile shear zones; ore elements are derived mainly from surrounding or deep-seated rocks; and the content of gold elements is negatively correlated to the ductile deformation intensity of the mylonite. The long-evolved ductile shear zone is the essential condition for forming shear zone type gold deposits or large gold deposits through su-perimposition of several gold mineralization types and is also the favorable area for looking for the shear zone type of gold deposit.
