Abstract

Due to the complexity of surface geological condition and subsurface structure of the thrust belts of foreland
basins in central and western China, the qualities of seismic data imaging are generally poor. In view of this situation, a
quantitative tectonic modelingmethod was put forward. The techniques such as seismic wave forward modeling, balanced
geologic section numerical simulation and structural physical simulation were applied to establish the final quantitative model. The tectonic deformation characteristics were analyzed from the aspects of the amount of
deformation, deformation mechanism,deformation time and deformation process. The proposed method was applied to
determine the geometry and kinematic structural parameters in Dushanzi anticline in southern margin of Junggar Basin,
and good results have been achieved.
