Abstract: | The Beni Snouss granite is a member of the late-hercynian Granites of NW Algeria. The Beni snouss Complex comprises an assemblage of two nested intrusions Tairet and Bouabdous. The studied intrusion, represented by a composite association of granites with dark microgranular enclaves, has a typical high-K calc-alkaline evolution, with peraluminous trend. U-Pb zircon geochronology yielded the minimum emplacement age of 297 ± 1 Ma. Mineralized quartz (±sulfide ) veins are hosted by granitoids in close spatial association with granitoids having quartz veins representing hydrothermal activities associated with them. Invisible gold occurs in a very small arsenopyrite minerals. Fluid inclusions were studied in vein quartz. They have salinities of 21 eq. wt.% NaCl. These fluids may represent late magmatic fluids associated with greisenisation and mineralisation. |
