SATELLITE IMAGE INTERPRETATION OF ZI JING GUAN DEEP FAULT IN NORTH CHINA

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.
