Abstract

Internal parting surfaces associated with fluidization tones up to 20b in length, occurring in the alluvial redbeds of Prince Edward Island contain secondary sedimentary structures resembling sole marks. These are described and their origin considered in terms of physical diagenesis. Rapidly escaping pore water in conjunction with load deformation within fluidized zones during dewatering and compaction of the redbeds are thought to have been the principal processes involved in the formation of these structures. RÉSUMÉ On rencontre dans lea lits rouges alluviaux de l’ile du Prince-Edouard des plans internes de rupture qui sont associés à des zones de fluidité mesurant jusqu'à 20 m de long et qui font voir sur leur substratum, des empreintes ressemblant à des structures sédimentaires secondaires. Ces structures sont décrites et on envisage une origine due a la diagenèse physique. L'éjection rapide des eaux interstitlelles accompagnté d'une déformation de charge au sein des zones de fluidité pendant la déshydratation et le tassement des lits rouges expliqueraient engrande partie la formation de ces structures.
