| Abstract: | Listric normal faulting and its fault-bounded blocks are the most significantstructural movement pattern in the extensional tectonic region. It is of practicalsignificance to study and master the structural deformation features caused bylistric normal faulting in extensional regions by using regional geological struc-ture, geophysical data and geodetic surveying. Based on the geometric andkinematic behaviors of listric normal faulting, the surface effects of crustaldeformation and dynamic features due to recent movement caused by listricnormal faulting are studied in combination with the geodetic data from theextensional region of the North China Plain. |
