Abstract :
Folding patterns in the Zagros thrust belt are highly influenced by both the mechanical behavior of its rock units and the activity of the Bedrock faults with each Zagrosian and Arabian orientation, and this factor significantly influences the upper deposit sedimentation patterns throughout many areas, and on other occasions it also affects facies distribution and alternate thickness changes. The main goal of this article is to assess the effect of Hendijan-Izeh Fault on deposition of Tarbur Formation (Maastrichtian) in Keynow anticline and its vicinity during field study, satellite imagery geological mapping; and using results from thin sections (33 samples), Four lithofacies were identified, which points toward a carbonate ramp depositional environment, whereas the sediments biostratigraphically display Maastrichtian age. The findings of the article demonstrate that with respect to the Hendijan-Izeh Fault, Tarbur Formation transitions into Gurpi Formation with distance, while Gurpi Formation is deposited where Tarbur Formation would be from the southern limb of Keynow anticline. Therefore, it is concluded that the Hendijan uplift was consequential during the time of Tarbur Formation deposition.
