The area has been subjected to E-W Variscan shortening responsible for an eastward-verging thrust. Although being stratabound, the mineralization is controlled by the local tectonic structures.

These dikes are accompanied by hydrothermal pockets of epidosite (epidote, quartz) at the base and veins of chlorite, albite, quartz, epidote and sulfides towards the top. Two stage of mineralizations have been recognized in these ophiolites. The first (phase 1) is early pre-orogenic, and the second, (phase 2) is late- to post-orogenic. In the Bou Azzer ophiolite phase 1 includes two successive paragenesis. Paragenesis 1 characterized by high temperature (350°C), high sulfur fugacity (fS), and low oxygen fugacity (fO2), includes cubanite, chalcopyrite, pink bornite, and sphalerite. Paragenesis 2, of lower temperature and higher sulfur and in oxygen fugacity, consists of digenite, covellite, and chalcocite. In the Khzama ophiolite, phase 1 is formed solely of sphalerite and chalcopyrite, the cubanite and the bornite were not observed. Phase 2, in both ophiolites includes veins o...
