| الوصف: | The Dehdasht Structural Basin, at the boundary of the southern Dezful Embayment and the Izeh Zone, is bordered by large anticlines with Cretaceous to Oligo-Miocene outcrops above hidden basement faults. The drainage system within the Dehdasht Structural Basin and the surrounding is considerably influenced by growth of the Gachsaran diapiric anticlines and salt extrusions and of the boundary anticlines. The Bangestan anticline in the NW of the basin uplifted 655 m since the Maroon River was diverted. Comparing the uplifts recorded in the topography of the large anticlines which are related to the Mountain Front Fault, to their structural amplitudes shows that the Khaviz anticline on the southern Dehdasht Structural Basin has more recent activity than the Bangestan and the Kuh-e-Siah anticlines. Variations of the local base levels along these anticlines with regards to their recent uplift values suggest 30 to 45% contribution of the thrust faults on their forelimb in the active deformation of the structures bounding the Dehdasht Structural Basin. ; This study is a part of the PhD thesis of the first author (KH) at Shahid Beheshti University of Tehran, Iran. HH is supported by the Shahid Beheshti University [grant No. D/600/3019]. We are grateful to Lucia Struth for providing the water divides and knick points for the drainage system within the study area and the surroundings. ; Peer reviewed |
