Field aspects of metabasalts and serpentinized peridotites. Photographs were captured at the Mont de Ritses (a, b), in the Mont de l’Etoile area (e–f), on the eastern slopes of the Aiguilles Rouges peaks (c, d) and at les Ignes (g, h). a, b Flattened pillow metabasalts. c Weakly deformed pillow basalts. d Mylonitic metabasalt cut by plagioclase vein. e Carbonated serpentinized peridotite displaying serpentine veins. f Static carbonation of serpentinized peridotite, pyroxene ghosts can be recognized, the matrix is composed of serpentine and carbonate. g Metasomatized diabase dikes intruding serpentinized peridotite beneath the Aiguilles Rouges gabbro. h Metasomatized diabase dikes intruding serpentinized peridotite, their margins are chloritized while the inner part is carbonated
