| Abstract: | The Iraqi territory is located in the northeastern part of the Arabian Plate covering the collision zone with the Eurasian (Iranian) Plate in the northeast. This collision, which is still active with convergent tectonics, has caused deformation in the rocks of the Zagros Mountains with different intensities. The deformation intensity decreases southwestwards with exerted stresses from the collision in the NE–SW direction. Depending on the deformation intensity and other tectonic factors, the Iraqi territory is divided into three main tectonic units, these are from NE to SW: (1) Shalair Terrane, (2) Outer Platform, and (3) Inner Platform. Accordingly, the Inner Platform is less deformed as compared to other tectonic zones. Neotectonic evidence has been documented across all tectonic zones of Iraq; even within the Inner Platform which was assumed to be a tectonically stable zone. This study presents different Neotectonic evidence and their role in updating the tectonic framework of Iraq, confirming that the so-called Stable Shelf or Inner Platform units, which are considered tectonically to be undeformed are deformed by Neotectonic activity.
