<p>The Tighza District, located in the NE part of the Moroccan Hercynian Massif, is renowned for its multiple mineralizations (W-Au, Pb-Zn-Ag). This Hercynian chain segment exhibits vigorous magmatic activity, characterized by granitic plutons, dykes, and lenses that extend over several kilometers. These rocks belong to a calc-alkaline series with high potassium content, formed in a geological setting that evolved from syn- to post-collisional conditions between the Upper Carboniferous and Permian. These magmatic associations can be divided into three events: The first event, marked by granitic intrusions, represents the peak of a subsurface plutonic body, forming a contact metamorphic aureole and syn-granite dykes. These dykes, composed of microdiorites, microgranites, and microgranodiorites, exhibit medium- to microgranular textures with biotite, plagioclase, K-feldspar, and quartz. The end of this event is marked by hydrothermal activity, leading to the formation of a quartz vein associated with W-Au mineralization. The second event corresponds to the crystallization of intermediate to felsic dykes (microtonalite, microdiorite, microgranite) belonging to the calc-alkaline suite, indicating a resurgence of magmatism associated with the underlying batholith. The last event is represented by (i) a dense network of dykes in southern Tighza, forming an E-W hypovolcanic complex of rhyolites and microgranodiorites, suggesting emplacement in a sinistral shear context. Disseminated sulfides in these dykes indicate they formed contemporaneously with the hydrothermal event linked to Pb-Zn-Ag mineralization. Furthermore, (ii) the microleucogranites, emplaced in echelon tension slots under sinistral shear controlled by the Tighza fault. They correlate with two-mica granitoids of the Moroccan Central Massif, marking the transition from the Hercynian orogeny to the Permo-Triassic extension.</p>
