| 摘 要： | 本文根据野外地质地貌调查,结合卫星影像解译和钻孔资料的分析认为,邯郸—邢台断裂是一条晚第四纪以来活动的断裂。根据断裂走向、活动时代及活动性质的变化,可将该断裂分为三段。临城—永年和永年—磁县段为全新世活动断裂,活动性质为右旋正断,晚更新世断裂的垂直滑动速率为0.25mm/a,全新世垂直滑动速率为0.47mm/a。磁县—安阳段为晚更新世时期活动断裂,活动性质为右旋正断,垂直运动速率为0.22mm/a,但全新世没有活动。

| Abstract: | New results of field investigations show that the Handan-Xingtai fault is an active reverse fault in late Quaternary.This fault can be divided into three segments in the light of its strikes,active ages and natures.The Lincheng to Cixian segment in the south is characterized by normal fault since later Pleistocene and Holocene,while the Cixian to Anyang segment in the southeast is dominated by right lateral displacement since later Pleistocene.The average vertical slip rates in the Lincheng to Cixian segmen... |
