Abstract

Typological zircon data compared to petrographic and geochemical study of Moroccan Massif Central granitoids (Oulmes, Zaer, Ment) indicates that the Oulmes granite and Zaer two mica facies belong to the crustal aluminous intrusive leucogranites. The Zaer biotite facies belong to the hybrid (crust+mantle) calc-alkaline granites; produced from a water-rich magma (low T index). The Ment leucogranites are, cogenetic with Ment granite. Both belong to hybrid (crust+mantle) calc-alkaline granites and crystallized from hot and drier magma (high T index). There is an abridged English version. -English summary
