This study identified a positive structural inversion related to detachment within the evaporites of the Miocene Gachsaran formation and diachronism in the deformation from NE to SW. Disharmonic tectonism was also observed, leading to a singular vertical succession with anticlines in deeper limestones (reservoirs) underneath shallow synclines. Finally, an earlier deformation controlled by previous deep-seated faults was proposed to explain the oil traps. ER -
