	The aim of this work is to characterize clays of Middle Eocene age from the Ghoufi-Atlas Saharan region, Algeria, in order to know the fields of their use and their eventual valuation. To this end, an outcrop sampling campaign was carried out across these formations. The samples collected were analyzed by X-ray diffraction (XRD), X-ray fluorescence (XRF), and Scanning Electron Microscopy (SEM). Potential samples rich in clay fraction were further analyzed using laser granulometry, physicochemical tests, and copper adsorption recovery tests. The results showed that the clay fraction, which varies between 71 and 86\%, are entirely represented Palygorskite, accompanied by 06{\textendash}18\% of dolomite, 03{\textendash}7\% of calcite, and traces of quartz as non-clay minerals. Further analysis showed that these clays have a cation exchange capacity (CEC) of 07 and 07.16 meq/100 g and a specific surface area (SS) of 57 and 60 m2/g. Copper adsorption tests have shown that fixation kinetics are very rapid and that these clays have a very high adsorption capacity.

	abstract = {
	The Algero-Tunisian confines (Tebessa region) belong to the southern Tethyan domain and the Monts Mellegue. This region is partly composed of Cenomano-Turonian carbonate outcrops; therefore, the investigated sections\&nbsp;highlight the black shale levels reported over a short period, around the Cenomanian-Turonian boundary. The lithostratigraphic study designated a depositional environment that emphasized a relatively deep, calm, and often confined ocean environment significantly shallower on the northern part of the study area. The facies lithology and distribution leads\&nbsp; to underline the pelagic influences during the upper Cretaceous and neritic throughout\&nbsp;the lower Cretaceous period. The\&nbsp;maximum thickness of the Cenomano-Turonian (1000\&nbsp;m) was recorded\&nbsp;in the southern zones and the\&nbsp;minimum (100\&nbsp;m) occurred\&nbsp; further north. This palaeogeographic organization persists\&nbsp;laterally in Tunisia as\&nbsp;the extension of the Constantine mole. The geochemical analyses reveal\&nbsp;that the maturity of the Cenomanian source rock is variable. Nevertheless,\&nbsp;the Turonian source rock \&nbsp;seems to be\&nbsp;at the beginning of the oil phase.

The high salinity coupled with groundwater level decline pose serious problems for current irrigation and domestic water supplies as well as for future exploitation. The statistical treatment of hydrochemical data by principal component analysis revealed two components related to salinity and pollution. The US salinity diagram illustrates that most of the groundwater samples fall in C3S1- C4S1 quality with high salinity hazard and low sodium hazard.},

		Le SASS couvre une superficie d{\textquoteright}environ 1\&nbsp;000\&nbsp;000 km{\texttwosuperior}, il est partag{\'e} par l{\textquoteright}Alg{\'e}rie, la Libye et la Tunisie. Il est situ{\'e} dans une zone hyper aride avec une recharge actuelle minime mais un grand volume stock{\'e}, {\'e}valu{\'e} entre 20\&nbsp;000 et 31\&nbsp;000 km3.
	

	
		Depuis 1970 {\`a} nos jours, l{\textquoteright}exploitation du SASS est pass{\'e}e de 0,6 {\`a} plus de 2,5 milliards m3/an., d{\textquoteright}o{\`u} des risques majeurs \&nbsp;de salinisation des eaux, de r{\'e}duction de l{\textquoteright}art{\'e}sianisme, de tarissement des exutoires naturels, de baisse de la pi{\'e}zom{\'e}trie, d{\textquoteright}augmentation des rabattements ou d{\textquoteright}interf{\'e}rences des p{\'e}rim{\`e}tres de captage entre pays{\textellipsis}Ce qui menace {\`a} terme la durabilit{\'e} du d{\'e}veloppement socio-{\'e}conomique engag{\'e} dans l{\textquoteright}ensemble de la zone.
	

	
		Pour parer au mieux {\`a} ces risques et surtout pour mieux s{\textquoteright}en pr{\'e}munir, un processus de coop{\'e}ration a {\'e}t{\'e} initi{\'e} depuis 1998 sous l{\textquoteright}{\'e}gide de l{\textquoteright}observatoire du Sahara septentrional (OSS) en partenariat avec les institutions en charge des ressources en eau dans les 3 pays.
	

	
		L{\textquoteright}importance de cet immense r{\'e}servoir pour le d{\'e}veloppement de la zone SASS et la n{\'e}cessit{\'e} de sa gestion durable et concert{\'e}e a amen{\'e} {\`a} une entente pour son {\'e}tude en plusieurs phases\&nbsp;: la caract{\'e}risation hydrog{\'e}ologique du syst{\`e}me aquif{\`e}re et sa mod{\'e}lisation, l{\textquoteright}identification des risques environnementaux et l{\textquoteright}inclusion de l{\textquoteright}aspect socio-{\'e}conomique dans des sc{\'e}narios de d{\'e}veloppement.
	

	
		Les ressources en eau du SASS sont tr{\`e}s faiblement renouvelables, environ 1 milliard de m3/an, vis-{\`a}-vis des pr{\'e}l{\`e}vements actuels estim{\'e}s {\`a} 2,5 milliards de m3/an. La prise en compte de cette donn{\'e}e a {\'e}t{\'e} d{\'e}terminante pour pousser les scientifiques {\`a} {\'e}tablir la meilleure mod{\'e}lisation conceptuelle possible du syst{\`e}me qui soit {\`a} m{\^e}me de permettre d{\textquoteright}envisager diff{\'e}rents sc{\'e}narios d{\textquoteright}exploitation de la ressource tout en tenant compte des perspectives de d{\'e}veloppement socio-{\'e}conomique de chacun des 3 pays.
	

	
		Les donn{\'e}es actuelles, quoique rassurantes, ne signifient pas l{\textquoteright}inexistence, {\`a} court ou moyen terme, d{\textquoteright}un risque de conflit autour de ces eaux transfrontali{\`e}res. En effet, le probl{\`e}me m{\'e}rite d{\textquoteright}{\^e}tre analys{\'e} {\`a} travers plusieurs indicateurs qui ont un impact sur ce risque.
	

	
		L{\textquoteright}objectif de cette note est d{\textquoteright}{\'e}valuer le risque de conflit autour des eaux du SASS {\`a} travers un indice global exprim{\'e} num{\'e}riquement sur la base de la combinaison de poids et de cotes de plusieurs indicateurs qui ont, directement ou indirectement, un impact sur le risque de conflit.
	

	
		L{\textquoteright}indice global de risque de conflit obtenu pour le cas du SASS semble refl{\'e}ter correctement la situation qui y pr{\'e}vaut actuellement. La comparaison de ce r{\'e}sultat avec ceux obtenus pour les eaux transfrontali{\`e}res du bassin du Jourdain (risque {\'e}lev{\'e}) et ceux du syst{\`e}me aquif{\`e}re du Guarani (risque faible), conforte l{\textquoteright}{\'e}chelle des valeurs adopt{\'e}e dans cette m{\'e}thode d{\textquoteright}indexation num{\'e}rique.
