mounds are capped by hard ironstone deposits. Paleogeographic models of paleolake formation in Dakhla have included spring mound development in connection
with shallow-water or lake-margin (Adelsberger 2008).
3.3 Sand Dunes
Dakhla Depression is surrounded by sand dunes and dune fields from nearly all
directions. The sources of these dunes lies far north on the southern fringes of the
Qattara Depression. From this context, Dakhla is an ideal “Oasis” since dunes are
scattered around from many directions (see Embabi 1977, Gad 1992, Embabi 2004).
3.4 North: (El Dakar Dune Filed)
From the northern direction, Libyan Plateau falls down the sand dunes across the
escarpments. The cuesta-back of dipping northwestern-ward to Farafra depression
gave a good chance to the drifting sands to accumulate in longitudinal dunes filed
(Fig. 29). As this field has no name on the maps, I will name it “El-Dakar.” This
