| Abstract: | The author introduces the basic feature of ductile shear belt and ore-contained term from Kuangoukou to Hongqigou. By the fault valve-earthquake pump-cyclically healed framework, the dynamic mechanism of fluid coupled ore-forming term, the procedure of this shear zone's forming and mature is explained. Meanwhile, the author discusses this shear belt tectono-dynamics promoting the process of the metallogenic system, handling the operating mechanism, controlling the movement and geometry of the ore-forming substances, and the ore-forming procedure, capacity and the difference. |
