Abstract :
Determining the direction of deformation migration in the fold- thrust belts, is one of the basic aspects for understanding the structural evolution of the fold and thrust belts. By studying the timing and mechanism of deformation and compare it with different regions of a fold thrust belt, it is possible to gain a better understanding the history of the structural evolution. The timing and development of deformation in the Zagros folded belt is one of the widely studied topics and the general belief is that collision of two plates of central Iran and Arabian began in Miocene, and gradually developed from the northeast to the southwest. According to the present study, the timing of folding of the Jaril anticline in the northern of Dezful embayment is estimated to be end of Middle miocene (Serravalian). The results of the present study indicated that the onset folding of the Jarik anticline in this area coincides with the deposition of the lower Aghajari Formation.
