| Mineralization of the Eburnean basement |
In this cratonized plinth, the eburnean orogeny is responsible of the gold bearing deposit formation of orogenic golden type whose the most important is the one of LOURIM (Tagragra and Akka buttonhole). Other occurrences are in Kerdou, Zenaga, Ighrem and Tata buttonhole. In this plinth, also exists a pneumatolithic mineralization on beryl, micas and feldspaths taken essentially in pegmatite seams. |
