Résumé

Injection of semi-fluid silt/water suspensions into semi-fluid sand/cement slurries resulted In the formation of a variety of structures at the Interface between the two materials. These structures resemble flute, load, groove and ridga-casts and form as a result of flow-moulding ('rheoplasis'). These experimental results complement earlier work' on certain natural occurrences of these structures and substantiate the hypothesis that they form as a result of post-depositional sediment movement and not through primary sedimentary processes. RÉSUMÉ L'injection de suspensions aqueuses sermi-fluides de limon dans des mélanges semi-fluides de sable et de ciment à produit une variete de formes à la surface de contact des deux matérlaux. Ces formes, qui resseablent aux empreintes de charge, flùtes, cannelures et crêtes, résultent du moulage d'une coulée ('rheoplasle'). Les resultats de ces expériences complementent des travaux anterieurs qui traitent d'exemples naturels de ces formes et appulent l'hypothèse selon laquelle ces formes résultent du mouvement des sédiments après leur déposition et non pas de processus sédimentaires primaires.
