The Tamlalt–Menhouhou gold deposit belongs to the Neoproterozoic–Palaeozoic Tamlalt inlier located in the Eastern High-Atlas (Morocco). It occurs in altered Upper Neoproterozoic bimodal volcanic and volcano-sedimentary units outcropping in the Tamlalt–Menhouhou area. Gold mineralization has been identified in quartz veins related to shear-zones...

Zircons from the polyphase Tamlalt-Menhouhou gold deposit were examined in order to define the age of the sodic metasomatism (albitization), which is assumed to be related to the primary gold mineralization. Magmatic and hydrothermal zircons were distinguished in albitized banded rhyolitic metatuffites (BRM) and in albitite on the basis of...
