L'étude minéralogique et pétrographique d'une ponce trachytique provenant des coulées pyroclastiques du volcan de Vico (Italie centrale) montre que l'altération des verres produit essentiellement une halloysite bien cristallisée avec conservation de leur texture. Les auteurs discutent les caractéristiques minéralogiques et structurales de cette argil
