Title: Quelques observations petrographiques sur le NW du massif de Levezou (Aveyron)
Abstract: Abstract The metamorphic series of the northwestern Levezou massif, Aveyron, France, is characterized principally by enrichment in silica and potash. This enrichment (possibly due to concentration of femic elements in small lenses in the migmatites) is not uniform, but is always present, both in the mica schists and paragneisses, which grade into migmatites, and in the greenstones bordering the migmatite massif.
