“…1). This area is characterized by a complex network of aborted asymmetric rift basins formed during the disruption of Pangaea around the Permian-Triassic boundary (Warme, 1988). The geometries of sub-basin were controlled by normal faulting oriented ENE mainly affecting Palaeozoic meta-sedimentary basement rocks (Frizon de Lamotte et al, 2008).…”

“…The idea of large-scale detachments and overthrusting within the crust (JACOBSHA6EN et al, 1988b;WARME, 1988) is still opposed by the assumption of only vertical crustal movements as the origin of these mountain belts (STETS & WURSTER, 1981).…”

Morocco has been for the past two centuries one of the top ten Pb-Zn producers with two thirds of base-metal production derived from three major Mississippi Valley-type districts (Touissit-Bou Beker, Upper Moulouya, and Jbel Bou Dahar). Collectively, these districts have produced more than 100 Mt of ore at an average grade of *3 wt% Zn and 4 wt% Pb. At the present time, none of the three districts is active. favorable fluid channels for metal-bearing brines into permeable host rocks and dissolution structures. The geometry of the orebodies that parallel the major alpine faults, coupled with lead isotopic constraints, suggest that the MVT mineralizing event occurred during midle Tertiary time (i.e., Cretaceous to Miocene) coincident with closing stages of the Alpine orogeny in the Atlasic orogenic belt. Alpine mineralization is thought to have been promoted by the mixing of older, high-temperature, rock-buffered, dense brines stored within the Paleozoic basement, and a downwelling, cooler fluid probably of meteoric origin. The resulting mixed brines were centered mainly on the basement high structure and its flanks, then flowed laterally away from the basement high and giving rise to the lower grade mineralization of the distal prospects. Fluid migration towards the ore districts could have been achieved either by a gravity-driven system (Touissit-Bou Beker, Mibladen, and Jbel Bou Dahar) or sediment compaction in the foredeep (Jbel Bou Dahar), or a combination of both. An alternative buoyancy-driven fluid convection model is proposed for the Touissit-Bou Beker MVT mineralization.
