Carbonate rocks of recent pleistocene age have been dredged in the siculo-tunisian area. They show an alteration of biogenic silica, volcanic glass and of some clay-minerals. The mechanism of alteration might be of biochemical order.Les roches carbonatées du Pléistocène récent draguées dans le détroit siculo-tunisien montrent une altération de la silice biogénique, du verre volcanique et de certains minéraux argileux. Le mécanisme responsable pourrait être de nature biochimique.Froget Claude.
