| Abstract: | This paper points out there are 4 stages of structural evolution in the gold ore area.Their geometrical feature and deformation mechanism corresponds to 3 ore-forming stages. After analysing the feature and evolution succession of the shear zone which occurs ill originaily bedded formation, the authors find out structural types of the gold deposit according tothe process from ductile shear deformation to brittle shear deformation. |
