Abstract : The North East Algeria is essentially composed of the metamorphic rocks, which are crosscutting, by Miocene massive granitic and microgranitic intrusions. In the region of Boudoukha, the crystalline basement is structurally controlled by multiple Alpine (Eocene-Miocene) faults (N-S, NE-SW), which facilitated the circulation of hydrothermal fluids. Many veins of polymetallic mineralization crosscut this region. The Boudoukha deposit is localized in the metallogenic area of Collo Lesser Kabylia; they consist of Zn, Pb, Cu vein types with traces of Ag, Au and Cd. Macroscopic and microscopic observations show varied textures (ribbon, disseminated and massive). Metallographic study revealed the presence of a characteristic mineral assemblage composed of sphalerite, galena, chalcopyrite, arsenopyrite and pyrite with minor amounts of silver and gold. Micro textural relations between these different sulphides indicate that this mineralization is the result of three stages. The results of preliminary chemical analysis (XRF, Atomic absorption and SEM) revealed the existence of mineralization with dominance of zinc. It should also be noted that this deposit is rich in compatible trace elements: Ni, Co and Cr. Also rich in gold, silver, arsenic and cadmium. In Boudoukha deposit, Analyses of sphalerite show mean contents of 8.93% Fe, 3.62% Pb, 1.36% Cd, 1.06% Cu, 0.26% Sn, 0.26% Ni and 0.15% Ag. This preliminary study shows that this deposit is associated with Miocene magmatism and can be considered as peri batholitic sulphide type hydrothermal mineralization.
