Characteristics of ground fissures located at Lintong-Chang'an fault zone

Lintong-Chang'an fracture zone and its relationship with earth fissures are briefly represented and it is testified in this paper that there exists earth fissures in the fracture zone based on two stratigraphic sections located in Lintong-Chang'an fracture zone.The result shows that the earth fissure developed into fracture zone has the same attribute as that of earth fissure upon hanging wall of Lintong-Chang'an fault.Also,the characteristics of the earth fissure and its activity law are analyzed on the basis of faulted bedding plane and the thickness variation of the same formation.It shows that the activity of earth fissure developed into Lintong-Chang'an fracture zone is varied in different sector:the western is relatively weak but the eastern strong,which is consistent with the fault's activity.
