Abstract：Fracture of Mount Qianfo is an important hidden fracture. To analyze the exact position of fracture, the habitat of rifts and the seismicity of fracture is of great significance. This thesis makes a comprehensive detection and analysis of this fracture with the techniques and strategies of Remote Sensing, Geophysical Detection, Geologic Structure and Engineering Geological Investigation, offers this fracture a precise localization and provides ananalysis for the seismicity property of fracture. This thesis also gives measurement result according to the tectonic characteristics of the fault, the geological features, fault materials and the overlying quaternary strata age, and makes sure that this fracture is the active fault in the early Pleistocene to Pleistocene. And there’s no significant sign of activity from the Pleistocene to now. The main movement property of fracture of Mont Qianfo is extensional normal fault, and also includes the left-lateral strike-slip motion. From the aspect of the relationships between the structures of the fault surface, the fracture had experienced polystage activities before the early and mid period of Pleistocene.
