Pétrographie sédimentaire dans la molasse de la région d'Yverdon

VERNET, Jean-Pierre

Abstract

Les minéraux lourds sont les repères stratigraphiques les plus importants et les plus sûrs dans la molasse du plateau vaudois. Ainsi la glaucophane caractérise la base de la molasse jusqu'au sommet du Chattien inférieur. L'augmentation de la teneur en épidote et la diminution de la teneur en apatite distinguent le Chattien supérieur. Il existe une similitude complète entre les formations molassiques des régions de Morges et d'Yverdon, tant au point de vue de leurs faciès lithologiques que de leur composition minéralogique. Il devient donc logique d'admettre le synchronisme de ces niveaux stratigraphiques locaux.
