Abstract

The silt and clay content of the topsoil progresses from nearly zero where vegetation is sparse to 18 % in the oldest and densest plant community. The humic acids released from the humus developing under the dense vegetation in the wet area accelerate leaching of Ca Co. In this process dune sand, moderately rich in carbonates and poor in silt and clay, becomes decalcified and enriched in silt and clay from dust. Further pedogenesis may lead to the formation of Hamra (Typic Rhodoxeralf). In the dry area dune sand rich in CaCO is also stabilized, but no prominent changes occur in composition. This material may be the parent material of Kurkar (calcareous sandstone).
