The Meatiq metamorphic core complex (MMCC) formed during the Precambrian as a result of multiple deformation and metamorphism in the Eastern Desert of Egypt. Structural, geochronologic, and fluid inclusion microthermometric analyses reveal a long formation/deformation history for the MMCC. This started with the break-up of Rodinia at ca. 800 Ma and continued until Pan-African collision at ca. 580 Ma. Between 800–780 Ma, rifting continued into sea floor spreading and oceanic crust formation. Synchronously, the Um Ba′anib granite intruded into an approximately 1.14 Ga old crust comprising migmatic amphibolites. Rifting was accompanied by the deposition of quartz- and mica-rich sediments. Between 660 Ma and 620 Ma, convergence between East and West Gondwanaland caused burial of sediments to a crustal depth of approximately 20 km and intrusion of calc-alkaline rocks. Subsequently, the meta …
