(A) Geographic features and localities in the northern sector of the Nile delta, including those cited in the text. (B) Map showing average thickness (in m) of Holocene section (CD) in sectors I, II, and III of the northern delta. (C) Lithologic aspects and physiographic features in the delta margin and offshore sector. Arrows highlight three major coastal shifts and reversals through time: I, coastline landward retreat in post-glacial time (ca. 16,000 B.C.) to early Holocene (ca. 6000–5500 B.C.); II, coastline seaward advance from early Holocene (ca. 6000–5500 B.C.) to late Holocene (ca. 2500 B.C.); and III, coastline landward retreat, once again, from late Holocene (ca. 2500 B.C.) to present.
