Distinct traces of aeolian abrasion in rocks and the statistical distribution of ventifacts on land surfaces of the serir type were investigated along a N-S profile across the western central Sahara. Wind fluting everywhere may be explained

La campagne d'incitation du gouvernement marocain à l'installation, et l'exode massif de la population sahraouie, expliquent que la majorité de la population du Sahara occidental soit constituée de colons marocains. Rabat a rejeté (mais non le

Rückschlüsse auf paläoklimatische Verhältnisse, abgeleitet aus Felsbildergenerationen in der westlichen Libyschen Sahara. (Generations of rock pictures of the western Libyan Sahara in its relation to the palaeoclimatic conditions)
Generations of rock pictures of the western Libyan Sahara are described and classified by the fauna depicted, by the techniques employed, and tentatively by stylistic development. They are related to radiocarbon dates. During the big-game and round
In this paper, the AA. analyse satellite images (Landsat TM, SPOT and SAR ERS-1) of the Tanezrouft Plateau (Sahara) together with observations in the field in order to find evidence of palaeo-channel networks that testify to intracratonic
In this paper reflections on the development of scarpfoot depressions are presented from a geomorphologic-geological, and sedimentological point of view. They are intended to clarify whether post-sedimentary relief development in Central Sahara

The Sahara is the world's largest source of aeolian desert dust, but precise information on specific sources of this material is poor. This paper uses daily data from the Total Ozone Mapping Spectrometer (TOMS) for 1999 to identify source areas
for major dust events and their trajectories of long-range transport. Two major sources areas are identified : the Bodélé depression and an area covering eastern Mauritania, western Mali and southern Algeria. Both of these major dust sources are primarily
Now an arid to hyperarid area, the north-western Sudan is known to be an important source of paleoclimatic information about the extent and intensify of the late Pleistocene wet phase in the eastern Sahara. To obtain representative evidence about

Iron-rich sediments in Dakhleh Oasis, Western Desert of Egypt, have been recognized as spring mounds and as archaeological sites where Paleolithic materials have been recovered. Detailed sedimentologic investigation and mapping of these features

. Deutschen Geographentag in Gottingen, 1979.. (The western escarpment margin of the Murzuk Basin, central Sahara as an example for the structural pattern of the arid relief)
Two sections of the Messak escarpment at the western margin of the Murzuk basin are presented in geomorphological maps and aerial photo mosaics and analyzed as to their pattern of landforms and geomorphic history. Relict forms of non-arid climates
in the older past and repeated climatic changes during the Quaternary together with differences in lithology and structure have resulted in two landform complexes for many Sahara tablelands. One type is presently subject to fluvial processes and is dominated
