The precise effects and significance of the repeated tectonic activities on the Arabian\u2013Nubian Shield, as well as their role in the rifting processes in the Gulf of Suez, are still not fully understood. However, the combination of zircon and apatite fission-track dating, alongside time\u2013temperature modeling, has proven useful in investigating these processes. This study reviews thermochronological data derived from basement samples taken from the Wadis Ba\u2019ba and Nesyrin regions, representing the northern end of the Gulf of Suez&#8217;s eastern flank. These data represent cooling ages decreasing southward. The reconstructed time\u2013temperature profiles indicated four significant episodes of rapid cooling, corresponding to the Neoproterozoic, Devonian\u2013Carboniferous, Cretaceous, and Oligocene\u2013Miocene periods. These cooling pulses were developed in response to four key tectonic events: (1) the post-accretion erosion event during the Precambrian\u2013Cambrian, (2) the Devonian\u2013Carboniferous Variscan tectonic event, (3) the Cretaceous break-up of Gondwana, and (4) the Oligocene\u2013Miocene rifting of the Gulf of Suez.<\/p>\n","protected":false},"featured_media":23247,"template":"","meta":{"_acf_changed":false},"journal-name":[221],"paper-tag":[233,231],"class_list":["post-23224","journal-paper","type-journal-paper","status-publish","has-post-thumbnail","hentry","journal-name-sasj","paper-tag-issue-1","paper-tag-volume-2"],"acf":[],"_links":{"self":[{"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/journal-paper\/23224","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/journal-paper"}],"about":[{"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/types\/journal-paper"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/media\/23247"}],"wp:attachment":[{"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/media?parent=23224"}],"wp:term":[{"taxonomy":"journal-name","embeddable":true,"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/journal-name?post=23224"},{"taxonomy":"paper-tag","embeddable":true,"href":"https:\/\/scientificassociation.org\/ar\/wp-json\/wp\/v2\/paper-tag?post=23224"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
