Abstract：The ductile shear zone type of gold deposit is one of the most important gold deposit types Deep ductile shear deformation causes Au to reactivate and differentiate from the source rocks,forming Au-bearing tectono metamorphic hydrothermal solution Meso-epizonal ductile-brittle deformation domain is the favourable site for gold ore accumulation The type of gold metallization are controlled by shear deformation level and features of the deformed rocks The important characteristics of the ductile shear zone type of gold deposit are that metallogenesis occurs after the ductile shear deformational stage;gold ore-bodies are mainly developed in some smaller ductile shear zones;metallogenic elements are derived mainly from surounding or deep-seated rocks;and the content of Au is negatively correlated to the ductile deformation intensity of the mylonite The areas near the orogenic belts are the favourable places for finding shear zone type of gold deposits.
