Abstract
In this research, changes in structural geometry of thrusting of the Aghajari anticline on the Marun anticline in Dezful Embayment (SW Iran) have been studied based on seismic reflection data. These two anticlines have a NW –SE trends and thrusting of the Aghajari anticline on the Marun anticline is located in North of the study area. The Marun anticline with visible plunge is forming in the south of study area and 4 and 5 seismic profiles, and most of deformation is concentrated in Aghajari anticline. Also, Marun anticline has formed in the middle of the study area, but thrusts not formed in this part of anticline and maximum thrusting of Aghajari anticline on the Marun anticline is visible. There is a shallow thrust in south limb of two anticlines in northern part and an upper thrust from Gachsaran formation exposed from progressive deformation and finally a shallow thrust propagate to surface in both anticlines in the end of NW parts of study area and back thrusts separate from main shallow thrust in two anticlines. But unlike the Aghajari anticline, an upper thrust from Gachsaran formation propagates to surface with progressive deformation in the Marun anticline showing low depth of the Marun anticline.
