Abstract：Zagros basin is one of the most important basins in the international petroleum industry because of its rich oil and gas resources and the complex structure system,and it is crucial to the understanding of the structural characteristics of Zagros ba-sin as to whether oblique-thrust fault-related-fold exist or not.Based on the fault-related-fold theories,and by using the dip an-gle domain analysis and fold axial plane analysis methods,geometric analysis of the structure of Buzurgan anticline in Zagros basin was carried out,and the time structure of T0 diagrams,the time domain horizontal slices and the seismic profiles parallel to the strike of the fault of Buzurgan anticline were made.On this basis,relying on the geometric feature recognition of oblique-thrust fault-related-fold,the geometry deformation style of oblique-thrust fault-related-fold of Buzurgan anticline was systemat-ically interpreted.And the forming processes of the Buzurgan oblique-thrust fault-related-fold in Zagros basin were reproduced by using the forward balanced cross section technique,the rationality and reliability of the above-mentioned interpretation about the Buzurgan oblique-thrust fault-related-fold was eventually validated.
