Abstract

The Kordofan sand is a deposit of unconsolidated surface sands covering large areas to the west of the White Nile in the central part of the Anglo- Egyptian Sudan and especially in the province of Kordofan. It is a typical wind-deposited sand of well-rounded quartz grains. The surface layers are pale buff to deep red, lower layers are colorless. The thickness ranges from a few inches to 100 feet. The dunes are mainly longitudinal ridges, but some transverse dunes also occur. The writer discusses the origin and age of the sand and relation to the underlying deposits.
