Structure analysis of Ezgeleh anticline

The Ezgeleh anticline is located in the northwest of Kermanshah province near the village of Ezgeleh. This symmetrical anticline is formed at the northwest - southeast direction of Zagros and is located in the Lorestan area. In the outcrop of this anticline, Ilam limestone formations are seen in the core of fold, marl and limestone of the Gurpi Formation, and Shale and Marl Formations of Pabdeh Formation are seen on the limbs of fold. This anticline is short and its hinged geometry is sharp. The axis of anticline have trend to the northwest and south-east and this anticline is Upright fold in terms of  axial and axial surface status. The Gurpi Formation shows thickening in the forelimb of this anticline. This fold, like most of the Zagros folds, is one of the fault-related folds. According to various diagrams, this fold is more in line with the geometry of the Detachment folds. Deviation of drainage around the nose of Ezgeleh anticline and existence of  several water gaps and wind gaps showed lateral growth of Ezgeleh anticline along axial surface in NW-SE direction. So this anticline is active fold and the seismic activity  of the region confirm it.
