Eburnean and Pan-African granitoids and the Raghane mega-shear zone evolution: Image analysis, U-Pb zircon age and AMS study in the Arokam Ténéré (Tuareg shield, Algeria)

► The studied region lies across the western boundary of the Saharan metacraton. ► Eastern basement protolith is dated at 1918±Ma and gneissification at 580±26 Ma. ► AMS fabric of the Eburnean granitic gneiss is related to the Pan-African tectonics. ► Pan-African granites are dated at 595±3 Ma and 582±3 Ma. ► AMS fabric is late-magmatic in most Pan-African plutons.
