Abstract :
High Zagros zone located in the northeast of Zagros Fold-Thrust Belt and comprises of NW-trending thrust faults. In Sabzkuh area, these thrust faults as forethrust and backthrust have accompanied with positive and negative triangle zones. These zones cause formation of the elevated Sabzkuh syncline on the hanging wall of the Dopoulan and Solaghan-Avardegan Fault as well as the Choghakhor embayment at footwalls of the Main Zagros and Solaghan-Avardegan faults. The horizontal bedding in the Ilam-Sarvak formations in the main faults footwall can be used as an evidence for the formation of the embayment. The elevated Sabzkuh syncline is associated with accommodation of limb wedge thrusts on the fold limbs. These structures show complexity of thrust faults geometry in the high Zagros and imply their initiation from the detachment horizons within the Lower Paleozoic/Hormoz Formation.
