The Great Sand Sea in Egypt : formation, dynamics and environmental change - a sediment-analytical approach / by Helga Besler ; with contributions from A. Bolten [and others].
The Great Sand Sea in Egypt presents the history of one of the large sand seas in the Sahara, beginning with the sand supply by fluvial transport from partly distant areas and also by local sandstone weathering. It also details sand as carrier of information and shows the possibilities of sedimentary analysis in dealing with such a topic. Simple measurements may supply important information (e.g. salinity measurements). Well known methods can be developed further to answer special questions. A wealth of information can be drawn from especially adapted sedimentological investigations. In the end, bits of information from different analytical sources can be put together to reveal the history of a large sand sea. *Analyzes different geological sources to decipher the history of the Great Sand Sea *Presents the possibilities of sedimentary analysis to interpret the history of an area *Develops well-known methods to further answer special questions.
