Kinematic Analysis of Folding Geometry in Aghajari Anticline (Dezful Embayment), Iran

Geometric style and deformation analysis of folding are two important aims of geological studies in Zagros، which is related to concentration of considerable of hydrocarbon reservoirs in anticlinal traps of the belt. In this study، evolution and geometry of Aghajari subsurface anticline (Dezful embayment) is considered based on 3D seismic data and well information. Based on illustrated structural cross sections، special attention was paid to geometrical variations of folding from fold pericline to central part of this structure. Geometrical complexity along and normal to the fold axis is related to implication of intermediate soft units in sedimentary pile. Fold evolution analysis shows limb rotation and hing migration which are the main mechanism for fold growth and passing from box to chevron style as well. Development of satellite structure around main anticlines in Zagros is promising features for hydrocarbon entrapment، which related to involment of decollement levels in folding.
