Geological features of ductile shear zone of Liuhe CountyAnkou Town in Jilin Province

Ductile shear deformation metamorphism occurred in the different historical periods and different tectonic settings, including the orogenic zone, Continental extensional environment, high pressure, craton environment and so on. The ductile shear zone is occurred late stage of the craton evolution, between Liuhe graben and Archean strata, it is dominated by ductile shear, with internal microstructure developed, including combination deformations structure and monomineral deformation structure. The rock type is mainly mylonite and mylonite schist. In Fullin map display an oblate ellipsoid, which is a typical degeneration type ductile shear zone. That has great significance on searching for ductile shear belt type gold deposit in the future.
