Descriptif
The main objective of this study is to identify the source of the sand in An Nafud (The Great Desert) sand sea, a source that must fulfill three requirements : 1. An adequate volume of source rock must have been available. 2. The source rock must have been erodible and accessible to eolian activity. 3. The source rock must lie upwind of the sand sea.
Related objectives are : 1. Determination of the areal distribution and characteristics of An Nafud sand (grain size, sorting, skewness, and kurtosis). 2. Determination of the heavy-mineral content of the sand, compositional percent of individual minerals, and their areal distribution. 3. Determination of the heavy-mineral composition and percentages of the Paleozoic sandstone strata flanking the An Nafud sand sea. 4. Description of recent and paleoclimatic conditions. 5. Description of morphology of An Nafud sand sea including dune types, interdune areas, vegetation and its influence on sand stabilization, and evaluation of geologic processes acting in the sand sea at the present time.
