La zone d'Echassières (Massif Central) concentre un grand nombre de minéralisations magmatiques (Sn, Li, Ta, Nb) et hydrothermales (W, Sn, Sb) en quantité économique ou sub-économique. Les nouvelles données minéralogiques et inclusions fluides des différentes paragenèses hydrothermales de la zone, les signatures chimiques en éléments traces de plusieurs minéraux stratégiques (principalement le quartz, mais aussi les micas et la topaze), traitées par un large panel d'analyses multivariées, et les nouvelles datations U-Pb sur rutile, zircon et monazite, ont permis de mettre en évidence trois évènements hydrothermaux minéralisateurs majeurs à trois époques de l'histoire varisque (anté-Tournaisien, Viséen et Westphalien). Ces minéralisations se...
