Abstract

New U-Pb zircon geochronology, field mapping, and Sr–Nd isotopic data constrain the Imilchil alkaline province of the Moroccan Central High Atlas to a restricted Late Jurassic window (ca. 163–149 Ma), establishing for the first time the precise diachronic relationship between salt diapirism and alkaline magmatic emplacement. The findings contribute critical constraints to Morocco’s geodynamic evolution and directly inform exploration models for the country’s deep mineral resources.
