However, in order to understand the overall geology of the region, the evolution of the region from the Late Proterozoic must be considered, as the present-day geometry (e.g. ![]() This study is primarily concerned with structures within the High Folded Zone. The orogen can be divided into two principal zones, the High Folded Zone, between the Main Zagros Thrust and the Mountain Front Flexure, and the Foothill Zone, between the Mountain Front Flexure and the Zagros Deformation Front ( Figure 1). The study area is located in the northwestern part of the Zagros Simply Folded Belt, an orogen resulting from the convergence between the Arabian and European plates since the Late Cretaceous ( Figure 1). Blanc et al., 2003 Alavi, 2004 Sepehr and Cosgrove, 2004 McQuarrie, 2004 Sepehr et al., 2006 Alavi, 2007) focus on the productive Fars Zone or the Dezful Embayment regions of Iran. The entire Zagros Fold-Thrust Belt varies in structural style and hydrocarbon occurrence along strike, and most previous structural studies (e.g. These anticlines are a result of convergence between the Arabian and Eurasian plates, where the deformation has propagated southwestward from the collision zone from Eocene time to the present ( Hessami et al., 2001 Csontos et al., 2012). Recently, the NW segment of the belt in the Kurdistan region of Iraq ( Figure 1) has come under renewed interest for hydrocarbon exploration, targeting the elongate anticlinal structures that characterize the geology of the region. 2,000 km from SW Iran into the Kurdistan region of Iraq and SE Turkey ( Alavi, 2004 Alavi, 2007) is anticipated to contain 49% of global fold-thrust belt hydrocarbons ( Cooper, 2007). One such belt, the Zagros Fold-Thrust Belt, which extends ca. We demonstrate that combining both structural and geomorphological methodologies can lead to a better understanding of the geometry and evolution of the trap-forming structures in the Kurdistan region of Iraq and thus is expected to be of interest to the petroleum industry.Ĭurrent estimates indicate that fold-thrust belts hold 14% of the discovered and 15% of the undiscovered global recoverable hydrocarbons ( Cooper, 2007). In addition, this study shows that the growth of the anticlines can be considered in 4-D, with consideration given to the interaction of the Zagros-age deformation with the pre-existing basement fabric. ![]() ![]() Results indicate that this methodology can be used to constrain potential thrust configurations at depth and the probable style of fold amplification and lateral propagation. To address these questions, this study combines field data, remote-sensing data concerning the structure and geomorphology of the anticlines, and structural modeling in order to produce robust interpretations of the geometries of the reverse fault structures that core the majority of these anticlines. Key questions to be answered concern the nature of the anticlines and whether the geometry of any associated thrusts can be predicted from surface geomorphology, as well the 4-D evolution of the area and along-strike continuity of the anticlines. In recent years, the Kurdistan region of northern Iraq has become an area of interest for both structural studies and petroleum exploration-related investigation. The Zagros Fold-Thrust Belt, extending from southern Iran, through northern Iraq and into Turkey, is characterized by elongate NW-trending anticlines that house large hydrocarbon accumulations.
