滦县—卢龙断裂的活动特征及其地震地质意义
The characteristics of activity of the Luanxian-Lulong fault and its seismic geological significance
摘要
Abstract
This paper studies the activity characteristics and seismic geological significance of Luanxian-Lulong fault by combining field surface geology and geomorphological survey,shallow artificial seismic reflection exploration and trough exploration.The Luanxian-Lulong fault is located in Luanxian and Lalong,generally towards NNE-NE,inclined W,with inclination of 60-70,and it is a reverse fault with 2-3 km wide and about 31 km long.The fault controls the development of Luanhe River Valley and its tributaries in some sections.Along the fault,there exists dynamic deterioration and forms obvious fault trough valley landform.According to the comprehensive means of shallow artificial seismic exploration,trough exploration,regional stratigraphic comparison and dating,it caused the deformation of quaternary strata,which was the active fault in the late Pleistocene.Although the Luanxian-Lalong fracture deformation is weak,the discussion believes that this can not rule out the possibility of strong earthquake in the future.关键词
