“…Pre‐collisional and syn‐orogenic calc‐alkaline magmatism (650–620 Ma), characteristic of the subduction period of the north ANS, was succeeded by post‐collisional magmatism (e.g., Jarrar, Manton, Stern, & Zachmann, ; Moussa, Stern, Manton, & Ali, ; Azer & El‐Gharbawy, ; El Hadek, Mohamed, El Habaak, Bishara, & Ali, ; Sami et al, ; Azer, Gahlan, Asimow, & Al‐Kahtany, ,Azer, Abdelfadil, & Ramadan, ; Abdallah, Azer, & El Shammari, ) including high‐K calc‐alkaline and alkaline rocks. The post‐collisional granitoid rocks of the north ANS, including those outcropping in the Eastern Desert of Egypt, provide significant information on these late magmatic phases and their contributions to the growth of the upper continental crust.…”
