Abstract. — Neogene Karst of Akhsass Table-land (N. 29° 25' - W. 9° 45') was formed on a planation surface cutting accross a complex geomorphic compression structure. Karst processing was directed by tectonic features and the pattern of fractures. Mega-structures divide the table-land in four units. Middle sized structures gave the direction of the surface shapes and underground karst. Exceptional ability of limestones and dolomites to karstic evolution is due to micro-structures. Quaternary up-lift of the table-land and a climatic change for drier conditions resulted in the selection of surface and underground drains related with the main fractures pattern.
