ABSTRACT: Asmari anticline is a
NW-SE fold in the Dezful Embayment sub-basin of Zagros. Fars group (Late
Moicene-Quaternary) is cropping out in the cores of anticlines in this area,
but Pabdeh and Asmari formations (Oligocene-Early Miocene) have cropped out
only in Asmari anticline in the Dezful Embayment. Therefore, it has formed a
unique exposure for above formations. In order to this situation, folding
mechanism of Asmari anticline has investigated in this research. According to
ourresults, Asmari anticline has
two mechanisms: flexural-slip in post-Cretaceous sequences(Khami-Quaternary) and fault-bend
folding in pre-Cretaceous sequences. So, there is a hybrid folding mechanism
that has introduced for the first time in this paper.
