oa Madoqua - Vegetation polygons in the central Namib Desert near Gobabeb

Volume 11, Issue 4
  • ISSN : 1011-5498



In the vicinity of Gobabeb both north and south of the Kuiseb River, well developed vegetation polygons have been noted. Previous workers have concentrated their efforts on the patterned ground features in the interdune valleys south of the Kuiseb. Two other areas of patterned ground development are descriptionbed and it is proposed that all three types are genetically similar. Desiccation of gypsum rich sediments in the soil horizons and / or the partially weathered bedrock horizon appears to have produced the polygonal fissure networks.
