Lithology and Thickness
A great part of Murzuq basin is covered by recent aeolian sands forming dune systems separated by deflation valleys. The highest dunes reach over 300m above the valley floors, and are concentrated in the basin's central portions. The sand grains show polished surfaces, are well sorted and lack bounding cement; the presence of conglomeratic pavements indicates ephemeral fluvial systems (flash-flood "playas") (Pierobon, 1991).
