The Beauvoir granite (Massif Central, France) represents an exceptional case in the European Variscan belt of a peraluminous rare-metal granite crosscutting an early W stockwork. The latter was strongly overprinted by rare-metal magmatic-hydrothermal

International audience; We describe the geological context of rare metal-bearing pegmatites from the Mangodara district (South-West Burkina Faso, Paleoproterozoic West African Craton) and discuss their petrogenesis and links with the host rocks. The

Potassium (K), thorium (Th), and uranium (U) are incompatible elements, with various degrees of mobility with respect to hydrothermal alteration or weathering and are taken as tracers for magmatic, fluid-rock interactions and mineralization. These el
