Application of Electrical Resistivity Tomography to the Detection of Buried Faults in Lake Sedimentary Basin: A Case Study in Tonghai Basin

In the present paper,electrical resistivity tomography was used to detect the west branch of Xiaojiang fault in lake sedimentary Tonghai basin.It is found that the location and attitude of this fault could be revealed out only in the deeper part of resistivity tomograms.Our results indicate that this fault has the strike of about N47°E,the apparent dip angle of about 57~66°and the apparent dip direction of NW or W in Tonghai basin,which is almost consistent with previous results.
