Abstract:: The secondary Haifengyuan Fault in the west branch of the middle section of the Xiaojiang Fault Zone in the northern part of Yangzonghai is selected as the research sample.By interpretation of the multi-source,remote-sensing data and the high-density electrical detection,together with field investigation and trench excavation verification,the spatial distribution and structural characteristics of the target fault are revealed.Results show that:①The Haifengyuan Fault is basically a straight and single fault.The linear characteristics of the fault on the remote sensing image are clear,and the macroscopic geomorphology is obvious.There are active landforms such as fault troughs,linear ridges,fault plug ponds,and water system dislocations along the fault.The fault is characterized as a sinistral strike slip movement.②The electrical structure anomaly of the inverted profile of the high-density electrical survey line near the fault-fracture zone are in good agreement with the location,the fracture-zone width and the dip of the fault confirmed by trench excavation.The overall strike of the fault is N20°E and the dip is SE,and the width of the fracture zone can be identified as 60 m.The geological survey finds that the Haifengyuan Fault faulted the overlying Holocene diluvium,showing significant active characteristics in the late Quaternary.The Haifengyuan Fault belongs to the Holocene active fault,which must be kept away from by the construction projects.③To carry out an active-fault detection in quaternary-covered area,it is advisable to take the comprehensive technical means of remote sensing and geophysical exploration,to determine the distribution and structure of the fault and then draw a conclusion in a geological way.Thus,the accuracy and reliability of active-fault location can be greatly improved.
