Abstract:In order to study the Quaternary activity characteristics of the middle section of Liaocheng-Lankao fault, we use the shallow seismic exploration and borehole combined section to detect the fault. We arrange five shallow seismic exploration lines and one borehole combined geological section are arranged across the fault. The borehole combining geological section reveals that the buried depth of the breakpoint on the fault is 61.4-64.5 m. Combining with the chronological results, the latest age of the middle part of Liaocheng-Lankao fault is the early late Pleistocene.
