Etude gîtologique de l’indice d’Azerou Madène (Ouakour), en Grande Kabylie.

Abstract

In the Great Kabylia, integral part of the chain of Maghrebides, the Kabylian range and the Northern part of Maurétaniens flyschs delineates a chaotic bonding corridor which is characterized by a mileage tectonic accident with an axis significantly East-West. The corridor, wide of several dozen to a hundred meters, includes as well the formations of the external range of Jurassic age to Eocene and flyschs units from the Cretaceous to Miocene, thus defining a thrust slice style. It is called commonly accident extra-kabyle by analogy to the accident intra-kabyle, more to the north between the metamorphic Kabyle basement and the internal range. This accident is emphasized by two mineralized occurrences, Azerou Madène, the focus of our study and Azerou N'Tohor, which have not been the subject of any metallogenic study. The nature of the sulphide mineralization is the blende, galena,chalcopyrite, and hematite and barite as gangue minerals. The morphology is in elongated body type indissemination with the form of Flyspeck and anastomosing veinlets. This index is cashed in the formations of the external range. The analysis of the mineralization shows that it is epigenetic and it presents two metallotects: structural and lithological.
