摘要: 紫荆关断裂最早由河北省地质局区调队命名于六十年代初期,是指位于河北省太行山东麓易县紫荆关至涞水县白涧地段,向北可延至岑南台,与沿河城断裂相接,向南伸至曲阳县灵山附近,走向北北东,倾向南东。断裂两侧地层发育和地质发展史有很大区别,故命名之。Abstract: A comprehensive geological interpretation of Zi Jing Guan deep fault at the west edge of North China Basin is made by using satellite image information,with region and geophysical data as background.Zi Jing Guan deep fault is located at the west edge of North China Basin in NNE-SSW.It stretches southwestward from east of Chicheng along Taihanshan Mountain passing Xiongershan and Qinling-Daibieshan folded belt,extended to the south flank of Huangling anticline.The total length within North China area is 900 km.Based on the geological features of the fault,it can be divided into three sections:north,middle and south.It was in embryo at the end of Middle Triassic time,formed in shape at the end of Late Triassic time,and the main body was completed at Late Jurassic.Magma intrusion of Cretaceous time brought the fault developement to a climix.
