-fjord regimes. The facies associations and ice-fjord conditions responsible for them form the basis for constructing a preliminary model for glacimarine sedimentation by tidewater glaciers, which can be used to interpret facies associations found

The morphology, sediments and processes associated with the construction of a moraine along the western margin of the ice-shelf in George VI Sound, Antarctica, are discussed. A conceptual model of the moraine is developed and may help to explain
Processes and models of Antarctic glaciomarine sedimentation
Modelling studies of underside of Brunt and Ross ice shelves suggest two main conclusions: 1. Ice-shelves are of major importance for sedimentation on the continental shelf. Bulk debris release occurs within the grounding-line zone which may
observed. Some attention was also paid to slope profiles and slope processes. Almost all slopes show concave or convexo-concave profiles and arc modelled by gravitative, gelifluction and washing processes.
Aavatsmark, Elise et Dahl. Les principaux processus modelant les versants des formes morainiques de Kaffioyry sont les suivants: la solifluxion et le ravinement, la solifluxion accompagnée de ruissellement, la solifluxion cyclique linéaire. (D'après l'A.).
