Groundwater systems and mineral resources
The groundwater system of the Western Desert (see Figure 4.2)
About 69 per cent of Egypt’s surface is covered by the Western (Libyan)
Desert, which largely overlies the Nubian Aquifer System (formerly called
Nubian Sandstone). This is a groundwater system of a complex structure
which extends over a vast area of 2 million km2
in Egypt, Sudan, Libya and
Chad. The geological origin of the sediment layers dates mostly from the
Mesozoic era, especially the Jurassic and the Cretaceous. Only a minor part
originates from the Palaeozoic era (Thorweihe 1990: 601ff ).
