The Oumjrane copper deposit in eastern Anti-Atlas is one of the top three major producers North Africa with an annual production exceeding 260,000 tons at average grade 1.4% Cu. Current inferred resources are estimated 5 million metric grading 1.5% Host rocks consist a succession Ordovician carbonate-free siliciclastic metasediments comprising sandstone- and quartzite-dominated cherty beds phosphate nodules, conformably overlain by Silurian organic-rich black-shales. In mine area, high-grade...
[Français] Dans les séries sédimentaires carbonatées d’Ali ou Daoud (Haut Atlas Central), minéralisations à Zn, Pb et Fe en amas stratiformes forment faciès de remplissage des karsts d’une plateforme carbonatée bajocienne. Le contrôle structural joue un rôle capital dans la localisation du gîte bordure sur failles synsédimentaires. niveaux dolomitiques encaissants minéralisations, assemblages argileux sont caractérisés par présence kaolinite dont teneur varie parallèlement avec celle...
Natural rocks are attractive storage materials for packed bed configuration, as they inexpensive, available, ecologically friendly and the most important not limited to working range of temperatures. However, their suitability is based on various criteria, which include thermo-physical mechanical properties, stability compatibility with both heat transfer fluid container. This work aims investigate potential three natural namely (leuco-gabbro, dolerite wherlite), were collected from region...

Les ressources été multipliées dix fois trois années pour atteindre 10Mt à 5,39% Zn 1,94%Pb 0,34%Cu. Cette méthodologie d’exploration basée sur les géologique géophysique devient plus utilisée dans l’exploration minière stratégique...
Natural rocks are a very promising option for medium temperature range (100-300 °C) thermal energy storage (TES) applications as they low-cost and abundant in nature. For concentrated solar power (CSP) plant working this range, the state-of art of TES (Two-tank molten salts system) is not an its materials has high solidification (e.g. 220°C Solar salt). Dual thermocline (DMT) system suitable it incorporates solid filler material. However, choice latter should be done wisely based on many...
