in the two depressions of Kharga and Dakhla for the effect of spheroidal weathering
processes in limestone disintegrated boulders thrown on the free slopes or valley bed.
Karst landforms are widespread, especially tufa and sinkholes (see Fig. 15).
Abu Tartur sector is occupied by badland topography. Here slope has about
500 km
2 of what called “all-slope” topography, where no scree, neither debris nor
talus cones or any segments of the classical slope profile.
