Étude de la minéralisation d’Ait Mislaine et Tala N’Tazert Située dans la zone de collage Socle Kabyle – Dorsale Kabyle (Grande Kabylie, Algérie du Nord)

Abstract

The great Kabylie is part of the internal domain of the North African Maghrebian chain. It is composed of two large units, the Kabyle Dorsal and the crystallophyllian base called the Kabyle base. The two study areas are an integral part of a chaotic contact zone that separates the crystallophyllian formations in the North and the Kabyle Dorsal formations in the South. This zone is characterized by a major accident of direction substantially East-West. It is marked by the presence of mineralization in the sectors of Tala N'Tazert and Ait Mislaine. The morphology of this mineralization is in veins. The latter are hosted mainly in mylonitic gneisses and very locally in shale. The nature of the mineralization is sulphide, it is magnetite often martitized, pyrite, chalcopyrite, hematite etblende. The gangue is carbonated, sometimes quartzose. It obeys structural control.
