Geochronology and geochemistry of Ediacaran volcanic rocks of the Tighardine ore deposit formation (western High Atlas, Morocco)

Evolution of Ore-Forming Fluids at Azegour Mo-Cu-W Skarn Deposit, Western High Atlas, Morocco: Evidence from Mineral Chemistry and Fluid Inclusions

“…The middle Cambrian is essentially composed of sandstone and pelite formations [39,48] (Figure 2). This lithostratigraphic succession is very similar to that of the nearby mining areas of Amensif, where similar hydrothermal transformations to those of Azegour were described [44,55]. The paleozoic series of Azegour records two Hercynian deformation phases [56].…”

Petrological and geochemical constraints on the origin of apatite ores from Mesozoic alkaline intrusive complexes, Central High-Atlas, Morocco

“…1b-c; Charrière et al, 2005Charrière et al, , 2009Haddoumi et al, 2002Haddoumi et al, , 2010Ettaki et al, 2007;Frizon de Lamotte et al, 2008, 2009Cavin et al, 2010;Saura et al, 2014;Haddoumi, 2016, 2017;Cavallina et al, 2018). The first Mesozoic sediments are Triassic red argilites and evaporites (mostly halite and gypsum) forming more than 1000 m-thick series which deposited within subsident basins and which cover unconformably a leveled Precambrian-Paleozoic basement (e.g., Du Dresnay, 1987;Piqué et al, 2002;Eddif et al, 2007;Ouabid et al, 2017Ouabid et al, , 2020Boukerrou et al, 2018;Karaoui et al, 2021). These deposits are generally interbedded with tholeiitic lava flows linking to the Central Atlantic Magmatic Province (e.g., Marzoli et al, 2019 and references therein).…”
