Mineralization of Co-Cr Au-Cu related to the pre-panafrican rifting event:
This event gave rise to mineralization in the two paleogeographical domains that it created:
- In the platform, pre-panafrican rifting is responsible for the origin of Bleida’s copper mineralization.
- In the oceanic area, we primarily see the mineralization of the Bou Azzer district of Co-Au (both genetically and spatially related to serpentines), and the gold bearing mineralization of Tafrent in the aggregation at Sirwa, encased by amphibolites in a volcanic rock context.
Precious metal mineralization in the arc context :
In this context, the most typical mineralization are at the Saghro and Ougnat massifs. This includes the Tiouit mineralization of Au-Cu, Imiter silver bearing deposit, Qalaat Mgouna gold bearing mineralization, Taourirt Tamellalt mineralization, and several filonian polymetallic mineralizations like at Boumadine, Tizi Moudou, Assif Imider, and scattering in the lower proterozoic in Ouarzazate.
Copper mineralization related to the Adoudounian basin :
With a typology reminiscent of kupferschiefers, these (post-panafrican) mineralizations are situated at the base of the infracambrian sequence on the Anti-Atlas proterozoic plinth. The paleogeographical constraint of these copper mineralizations is demonstrated by their localization near and around the precambrian paleo reliefs and their position at a regional and stratigraphical level.
