<\/a>[…] Dans le cas de la salle de la Verna, le socle hercynien est localement compos\u00e9 de calcaires d\u00e9voniens. Gr\u00e2ce \u00e0 la position et \u00e0 la nature des remplissages de la galerie Aranzadi, perch\u00e9e 100 m au-dessus de la salle de la Verna, on sait que la rivi\u00e8re s’\u00e9coulait il y a environ 200 000 ans dans cette galerie, ce qui n’est plus le cas aujourd’hui.<\/p>\n
