|Abstract:||Our study area is located in the Northern Sahara east of the Algeria, in the Valley of OUED Righ. Share its geographic position at the gateway to the desert and its altitude level from - 25 to-50 m from the sea level, it remains a field little operated on the study of the dynamics of the landscapes and soils. This contribution is a first mapping approach. It is based on the methodological confirmation and the model developed by the laboratory of geology of the University of Reims (France) team. Selected ground stations are defined on the basis of a well-established sequence, to highlight the spatial outline of soil evolution. Physico-chemical analyses of the different geomorphological levels of soil combined with mineralogical treatments performed in the x-ray diffractometer show that the spatial distribution of pedogenic features was significantly correlated to their positions on the geomorphic units.|
