ABSTRACT
During the Phanerozoic, Egypt was an exorogenic foreland receiving sedimentation affected by intermittent vulcanicity. Vulcanicity, and igneous activity at large, repeatedly occurred mainly in relation to the fracture system which originated in the Late Precambrian. Periodical reactivation of these older fracture zones throughout the Phanerozoic gave way to different types of plutonic and volcanic rock assemblages.
