    <abstract>Cet article présente une étude géochimique des terres rares de roches et de minerai du gisement du tungstène du djebel Aouam (Maroc central). La distribution des lanthanides dans les roches sédimentaires ne subit aucune modification importante au cours du méthamorphisme thermal. Par contre, les roches affectées par le méthamorphisme hydrothermal présentent d'importantes variations dans la composition en lanthanides. L'analyse de la distribution des terres rares montre que les fluides minéralisateurs dérivent probablement d'intrusions acides et spécialisées</abstract>
