FORWARD BALANCED CROSS SECTION OF THE DACHIGAN STRUCTURE OF EAST SICHUAN

The hangingwall deformation of the overthrust under severe compression may be revealed by using Suppe's fault-bend folding approach.On the assumption of the classical computation of the forward balanced cross section,the program presented in this paper for computing the forward balanced cross section is based on Suppe's geometric model.This program is extended not only to simplify the processing of the computation on the geometric fault,but also assist the user in gaining the parameters of the initial fault by William's inverse method.The certain forward balanced cross sections can be simulated once the number of faults and their structural interpretation models are given.In this paper,the balanced cross sections of the Dachigan Anticlinal Structure in East Sichuan is computed and plotted by this program.
