The Missing Link in the Genesis of the Lower Paleozoic Copper Deposits of the Anti-Atlas (Morocco): The Late Triassic Central Atlantic Magmatic Province Event

Copper mineralization in the Lower Paleozoic sedimentary cover of Anti-Atlas (Morocco) is continually being revised not only to improve its mining capacity, but also determine origin, which remains a matter debate. As evidenced by various models proposed, related research fragmented, localized, and confusing. The origin copper shared between synergistic epigenetic processes or superposition two processes. Based on new tectono-magmatic data reinterpretation ore structural arrangement, we propose link last concentration deposits Late Triassic–Early Liassic CAMP (Central Atlantic Magmatic Province) tectono-thermal event, as significant three NE–SW corridors affected extensional faults, some are filled with dolerite magma. heat flow generated mafic dykes within these reactivated causes mineralized fluids up well into layers, depositing material rich juvenile leached copper, even mixture two. In cases, trapped fracture systems that accompany passive folds initiated normal faults. other can infiltrate bedding planes, karst caves, formed during carbonate exhumation. Notably, extensive faults systematically early Hercynian structures, suggesting they belong post-Hercynian episode. During Triassic, global fragmentation Pangaea supercontinent was manifested stretching continental crust at margin northwest Africa, simultaneous opening Central Ocean emplacement magmatism. This often overlooked tectonothermal event must be considered remobilization reconcentration Morocco.
