Africa stands on a tectonic plate that is advancing north towards Europe. North Africa has a number of structural units that influence the outlines of the coast, generally with an E–W trend (Orme 2005). The Nile delta dominates the Egyptian coast ( Egypt (Mediterranean)), where beaches and dunes are of quartzose sand supplied from river distributaries, but these pass westward into beaches and beach and dune ridges of calcareous sand, including Pleistocene dune calcarenites. Beach rock is commonly exposed.

In western Egypt and  Libya, the coast is low-lying with cliffs cut in Tertiary and Quaternary formations, including dune calcarenite. The Jebel el Akbar range in Cyrenaica (E. Libya) forms steep rocky coasts with terraces at several levels, then the low-lying coast between Benghazi and Cape Misratah, intersecting the Sirte Basin (filled with Tertiary sediment) is fringed by dune-capped barriers, lagoons, marshes and supratidal flats, notably Sabkha az Tayurglia. The Jabal Tarhuna...
