“…Enormous volumes of sedimentary rock debris have been removed from the Qattara Depression by deflation [Said, 1960;Squyres and Bradley, 1964] [Norris, 1969], southern Africa [Logan, 1960], North Africa [Alimen, 1957], and Australia [Twidale, 1972] have suggested that relative redness of sand increases with age of the dunes. The progressive reddening of desert sands, due to the weathering of heavy mineral grains and ferruginous clay particles, first to yellow limonite and then to red hematite, has been described by Folk [1976].…”

“…Earlier studies of Upper Pleistocene sediments along the northern edge of the Sahara desert focused on the interior eastern valleys (Alimen et al, 1966;Conrad, 1969;Williams, 1970;Littmann & Schmitt, 1989) or on dune coastal areas (Rognon & Coudé-Gaussen, 1987, 1996Petit-Maire et al, 1987). These studies did not focus exclusively on fluvial morphodynamics, generally did not consider alluvial deposits older than the limit of the 14 C method, and came to varying conclusions.…”
