In the north eastern of Algeria and between the two barriers of mountains, Hodna in
South and Babors in North, situated a vast plains, commonly known as the Setifian High
Plains. This zone occupies the central part of the wilaya of Setif, and it's a part of the externe areas of the Alps, eastern Algeria, between the Tellian slicks in the North and the forward land autochton in the South. It is considered a closed continental basin, filled by Neogene and Quaternary deposits.
The genesis of evaporite deposits caused by the lagoon system that prevailed in the Triassic era with an arid climate and a high degree of evaporation which led to the precipitation of ions, Ca ++ So3--, Na +, Cl-, giving salt deposits and gypsum.
The spatial distribution, and the surface movement of the Triassic evaporite formations in the Setifian High Plains would probably caused by the phenomenon of overlapping slicks of alloctons to the south. We find five (5) evaporite formations dating from the Triassic; Guellal, Koudiat el Bassour, Methgoub Ras, Draa El Djebbas and Jebel el Garsa.
The principal minerals related to Triassic outcrops are represented essentially by evaporite deposits (gypsum and rock salt) .The particularity is marked by the presence of metallic minerals (iron and copper) in the blocks associated with evaporites Koudiat El Bassour.
The iron mineralization associated with copper, is hosted mainly in carbonate rocks, considered by the ancient writers as an infraliasiques formation. The morphology of the mineralized bodies is characterized essentially by a vein shape and stockworks type.
The mineralogical characterization by XRD and metallographic microscopic observation shows that the mineralization is usually oxidized brown-black (hematite, goethite, limonite) developed on iron carbonate (siderite, ankerite) associated with a few sulphides (chalcopyrite covellite, pyrite) and copper carbonate (malachite).
Gypsum deposits are widespread in all the Triassic outcrops of the region; it comes in four (4) forms (fibrous, crystalline, microcrystalline and grainy). The Gîtologics characters, the mineralogical characterization by XRD and chemical analysis by fluorescence X show that the gypsum is characterized by a variation of quality and quantity in an outcrops to another. As such, the economic importance gypsum deposit is observed in the Triassic of Guellal.
Contrary to gypsum, rock salt (halite) is prevalent only in the depth of the Triassic
outcrop in Guellal, and is forming a deposit of a great economic importance.
Geological, gîtologic and chemical characteristics of the rock salt deposits are the source of economic interest. Geophysical, mining and hydrogeological works of research in the diapir, which resulted an exploitation of salts for human consumption and industrial purposes.
The exploitation is more methodical, it is provided by the ENASel.Diplôme : Magistère En ligne : ../theses/sc-terre/MEZ6885.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10208 Les formations évaporitiques triasiques des hautes plaines Sétifiennes (NE Algérien) : Répartition et caractrisation des substances minirales associées [texte imprimé] / Aboutaleb Mezerzi, Auteur ; Abdeslam Demdoum, Directeur de thèse ; Ramdane Marmi, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2015 . - 178 f. ; 30 cm.

During recent decades, the area of El Ma El Abiod was marked by intense drought (erratic rainfall, higher temperatures and high evapotranspiration) also overexploitation of water reserves resulting a very significant downwash groundwater level of the Miocene tablecloth, which are the main source of food in the region; This leads to progressive desertification of the plain.
From the analysis of the current situation on the ground, this work helps to explain the operating mechanisms of the water of Miocene sands from its boundary conditions to its hydrodynamic and physicochemical characteristics, namely presence of pollutants and their sources.
This study is based on the development of an inventory of pollution sources, taking into account several factors, such as lithology land and climatic conditions, the location of discharges from sewage, farming and animal husbandry.
The vulnerability of groundwater in the plain of El Ma EL Abiod depends on the major expansion of the industrial, agricultural and urban context Despite a relative wealth of potential water resources, economic growth accompanied by industrialization, urban concentration accelerated and modernization of agriculture, led to a large increase in demand for water and therefore a high degree of pollution, monitoring degradation of water quality in the plain.
