Research subject. The article presents the results of dating two dolerite dikes differing in geochemical features from a section along the Iset river in the area of Smolinskoe settlement (the Eastern zone of the Middle Urals). Materials and methods. The dating was performed by an U-Pb ID-TIMS technique for single zircon grains using an artificial 205Pb/235U tracer in the laboratory of geochronology and isotope geochemistry of the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences. The lead isotopic composition and uranium and lead concentrations were measured using a Finnigan-MAT (RPQ) seven-channel mass spectrometer in dynamic mode using a secondary electron multiplier and RPQ quadrupole in ion counting mode. Results. The dikes were dated 330 ± 3 Ma and 240 ± 2 Ma. Conclusions. The research results indicate different ages of dolerite dikes developed within the Eastern zone of the Middle Urals. The oldest of the two established age levels corresponds to the Early Carboniferous era. This fact, along with the proximity of the dolerites to the petrochemical features of the basaltoids of the Early Carboniferous Beklenischevsky volcanic complex, allows these bodies to be considered as hypabyssal comagmates of these volcanics. The youngest obtained age level – Triassic – indicates that the introduction of some dolerite dikes was associated with the final phases of the trapp formation developed rarely within the eastern outskirts of the Urals and widely further east in the foundation (pre-Jurassic basement) of the West-Siberian Plate.

The Arab Gulf region in particular, and with it the entire Arab region in general, is witnessing multiple challenges and conflicts, escalating, in a way that reflects the presence of overlapping in the dimensions: internal, regional and international, which imposes important effects on Iraq. Iraq is part of the Arab Gulf region, and it interferes with it: historically, geographically, ethnically, and politically. It cannot be overlooked that Iraq was in historical stages that was considered the dominant force in this region, especially in the stage of the civilization’s dominance before the role of Iraq and its place in civilization declines. Today, the region is witnessing multiple challenges, which began with the escalation of regional sectarian political events associated with the event of the occupation of Iraq, with a tendency to disturb the regional balance due to the dismantling of the capabilities of Iraq, and the matter came to the loosening of regional conflicts due to what the region is going through, and the perspective of the active forces in it, which has overcome the perspective The struggle for cooperation. The entry or presence of the international worker in the regional conflicts in the Arab Gulf region caused the intensity of the conflicts to multiply instead of settling them, and Iran has presented on more than one occasion that it has the capabilities to implement the option of closing the Strait of Hormuz or impeding the freedom and safety of maritime navigation in international waters in the Arabian Gulf, And the matter was not related to the US sanctions regime on Iran in the year 2018 and beyond, but it is before it.     The Iranian threat to close the Strait of Hormuz at the very least, or any development in the regional conflict in the region, can damage the interests of Iraq and its security, for two reasons: First, most of Iraq’s trade passes through the waters of the Persian Gulf, and the second is that there is an overlap between Iraq and peoples and countries The region, and just as sectarianism moved from Iraq to the region after 2003, the Gulf conflict and tension can move into Iraq or affect Iraq’s policy. Iraq should search for political alternatives that help it in dealing with the developments of the conflict in the Arab Gulf region. Perhaps this research presents some of the options and alternatives that can help the Iraqi decision-maker, if there is an important development in the Gulf-Western conflict with Iran
