| 摘 要： | 通过口泉断裂1/5万地质填图,调查了口泉断裂中段(上神泉至杨家窑段)晚第四纪以来断错地貌特征.从山麓麓原面到山间沟谷河床一共可以划分出5级层状地貌面,最顶部(第5级地貌面)为山麓剥蚀面,推测为形成于新近纪的唐县期夷平面;第4级地貌面由大河间T3阶地以及山麓地带发育的同期洪积台地组合而成,形成于中更新世末、晚更新世初;第...

| Abstract: | Kouquan Fault is located in the north part of Shanxi graben which controls the west edge of Datong Basin.Two M61/2 earthquakes happened in the west side of basin in historical time,and there has been a concern about the future hazard of the fault.However,previous researches on Kouquan Fault were limited only in several points,especially,there was lack of measurements and dating data.Based on the 1:50000 geological mapping of Kouquan Fault,the paper investigates the late Quaternary faulted landforms of its m... |
