The fluid action in the ductile shear zone is a complicated tectonic physochemical process coupled with the mechanic and chemical process, and is also a self-organizing process. It not only affects the deformation mechanism as well as mineral constituents and chemical components of rocks and accelerates the growth and development of deformation structure, but also controls the reactivation, migration, enrichment and precipitation of ore-forming substances of gold deposits hosted in the ductile shear zone. Based on this review, authors indicate that the readjustment of mineralogical and chemical compositions and volume changes are the main research areas of the fluid action in ductile shear zone. The study on the fluid action in ductile shear zone will be carried out in the following aspects: evolution history of tectonicfluid, tectonic physicochemistry, and the strain model and its features.
