Northerly Movement of the Arabian Plate

Northerly movement of the Arabian Plate resulted in collision with the Anatolian Plates first producing the E-W trending anticlines followed by the stress introduced against the Iranian Plates in NE-SW direction resulting in NW trending anticlines of NE Iraq; some are overprinted over the Anatolian trend in N Iraq
