New geochronological and geochemical data are presented on Early Cambrian granites from the Ambatondrazaka area in east-central Madagascar. U–Pb zircon dating reveals that these granites were emplaced at ∼520 Ma within a post-collisional setting.

International audience; Bastnaesite and monazite deposits of the Ambatofinandrahana region of Madagascar are closely associated to an alkaline to peralkaline complex of Panafrican age (similar to 540-570 Ma; Ambalavao suite), composed essentially of
