According to a large number of measured data on the macroscopic and microscopic structures in Shanhu orefield, Zhongshan County, Guangxi, the authors discribe the major types and property of structural deformation, especially the ductile deformation, and determinate the mechanism and division of the structural deformation in the orefield. Based on five kinds of structural dynamic analyses, the authors establish the structural deformation history since the Indosinian movement, and discuss the relation between the deposits and structural deformation.
