Je tiens à exprimer ma reconnaissance à toutes les personnes qui m’ont permis de mener à bien ce travail. Si j’oublie une personne dans cet exercice, et je le ferai sans doute, je m’en excuse d’avance. Comment pourrais-je exprimer ce sentiment indescriptible en quelques mots et en si peu de temps pour Mr le Professeur Menani Mohammed Redha, mon Directeur de Thèse, sans lui cette thèse ne verra jamais le jour. Je tiens à lui exprimer toute ma reconnaissance de m’avoir proposé ce thème qu’il a suivi de près et soigneusement corrigé. Ses conseils précieux et ses critiques ont été un apport vital pour cette thèse. Je le remercie également pour la confiance et le temps qu'il m'a donnée de m'avoir initié dans le domaine de la recherche, malgré ses responsabilités et ses préoccupations. Ni les mots, ni un langage gestuel ne sauraient traduire avec justesse mes sentiments ; ni le temps, même une éternité, suffirait pour la remercier assez… Mes remerciements s’adressent particulièrement à DRIAS Tarek d’avoir accepter de présider mon jury de soutenance, aux membres examinateurs : CHABOUR Nabil ; Professeur à l'université de Constantine et BOUMAZBEUR Abderrahmane ; Professeur à l’université de Tébessa, je leurs serai reconnaissant pour le temps qu’ils auront consacré à lire cette thèse et qui nous font honneur de siéger pour évaluer. Mes remerciements vont également à tous mes enseignants des départements des sciences de la Terre des universités de BATNA et de Constantine sans exception. Un grand Merci pour Madame DIB Henia pour leur précieuse aide dans les moments critiques. Mes vifs remerciements à tous les enseignants et les collègues dès le primaire jusqu’à l’université. Je ne saurai oublier dans mes remerciements mon épouse KAMILA qui a supporté mes préoccupations et mon stress ainsi que à mes enfants ICHRAK, ARUDJ et MOHAMED EL AMINE, je leurs dédie cette humble œuvre. Enfin, certaines personnes méritent un remerciement spécial : celles qui ont été à mes côtés dans les moments les plus difficiles. Je les remercie de croire en moi lorsque j'ai de la difficulté à croire en moi-même. A mes très chèrs parents, mes sœurs et mes frères avant tout et pour tout, que j’adore et je souhaite toujours les voir à mes côtés, je dédie cette thèse.
