Index. décimale : 550 Sciences de la terre Résumé : tract The main purpose of this work was the characterization of minerals associated with evaporite Triassic formations of the Setifian High Plains.
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 : https://bu.umc.edu.dz/md/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 . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2015 . - 178 f. ; 30 cm.

three communicable diseases (Brucellosis, Tuberculosis and Foot-and-Mouth Disease) in the
district of Souk Ahras in north-eastern Algeria, between November 2015 and June 2016.
Obtained results on tuberculosis and brucellosis during the year of 2015 showed No significant
difference in the suspected mean annual frequencies by veterinarians and those reported by the
DSA of Souk Ahras district, with 5.37% for Tuberculosis and 2.50% for Brucellosis. Only FMD
with a frequency of 4.58% was significantly different, where the frequency reported by
veterinarians was higher than that reported by the DSA.Diplôme : Magistère En ligne : ../theses/veterinaire/REZ7029.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10570 Contribution a l’etude de la frequence et de la repartition des principales maladies bovines a declaration obligatoire dans la wilaya de Souk Ahras.

dactylifera L.) in the oasis of the Zibans region (Biskra) for three consecutive years (2010 to
2012) and was dedicated to the study of the most distinctive varieties in term of phenotypic
criterion. Trough some statistical tools (PCA and FAC), we identified the discriminating
characteristics and / or similar between the different genotypes. Particular attention was paid to
the presence, location and distribution of these varieties in the vast region of Ziban related to the
environment of this area.
The results showed an efficiency of the morphological characters (quantitative and
qualitative) of fruits and leaves by highlighting the differences and similarities in genetic
patrimony.
A very large varietal diversity was found in the oasis of Sidi Okba and Tolga, almost all
of that phytogenetic potential is in adequacy with the specific bioclimatic conditions of the
region.
