Abstract: Five kinds of fault rocks and thier structures concerned have been discribed respectively along the Tancheng-Lujiang fault zone at the recent erosion surface. It is clear that the two-phase deformation on the sence of mechanics commonly in various scales, in which both brittle and ductile deformation components are presented through faulting. On the basis of these inverstigations, a model for earthquake generation in the large fault zone has been discussed.
