Comparison between the Northern Thrust zone and the Zagros Thrust zone of Iraq reveals some basic differences between them. The differences are related to the timing of the opening and closure of the Neo-Tethys ocean. This implies that the two processes were diachronous. The Arabian indenter represents a protrusion and irregularity in the shape of Arabian plate margin. The indenter resulted in earlier collision in the Northern Thrust zone in comparison with the Zagros Thrust zone.
The basic differences between the two Thrust zones include the presence of Paleozoic rocks in the Northern Thrust zone, lesser thicknesses of the Mesozoic and Cenozoic rocks and the near complete absence of igneous bodies or exotic terranes. On the contrary the Zagros Thrust zone is characterized by the thick Mesozoic and Cenozoic sediments, plenty of igneous bodies and volcanic extrusion as well as thick flysch sedimentation exemplified by the Tanjero Formation. These differences were deciphered by the style and timing of the opening and closure of the neo -Tethys ocean during a complete Wilsonian cycle
