- Abstract:
- The south foot fault of Maomaoshan Mountain(F1)and the north foot fault of Jinqianghe River-Maomao-shan Mountain(F3)develop along the edge of Anyuan Basin. We conducted high-density resistivity surveying combining with boring data across F1 and F3. The results show that F1 cut the 3rd terrace which formed in late Pleistocene, and the last activity was extensional normal slip by echelonment falling down toward the basin. F3 stroke zigzag and cut the 1st alluvial-proluvial terrace and Holocene stratum with large displacement of fault and wide fracture zone in bedrock, and the last activity is the continuous falling around the fault. The survey confirms the characteristics and locations of the faults along the basin edge, which provides the evidence for engineering stability evaluation and construction.
