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.

结果表明,F1断层错断了盆地区内晚更新世晚期至全新世早期的Ⅲ级阶地;受拉分构造的影响,该断层最新活动显示了向安远拉分盆地方向迁移的阶梯状递减的张性正断裂性质。F3断层在走向上呈锯齿状,错断了山前Ⅰ级冲洪积阶地及全新统至上更新统地层,断距大,基岩破碎带宽,新活动主要表现为断层附近原地连续沉降。
