摘要
The Huangzhuang-Gaoliying fault is an important active fault in the Beijing plain area.The serious disasters of ground fissure have occurred along the Miaocheng-Gaoliying section,which have caused a lot of wall cracking and road damages.It indicated that the entire Quaternary strata were broken by the fault and the position of fracture surface on the ground was completely consistent with that of ground fissures from the trench excavation in the Xiwanglu Village.Samples were extracted from the trench with optically stimulated luminescence (OSL) and sporopollen dating.The results show that the formation age of the strata on both sides of the fault ranged from 13 ka to 22 ka, namely Late Pleistocene. In addition,it demonstrates that the Huangzhuang-Gaoliying fault is still in activity from the development of the ground fissure.
