Resumo

Tlie soft bottoms of the fiord inlets udjacent ro rhe glacial system of "Campos de Hielo Sur" are studied. A sedimentological characterization is mude. resulting in the recognition of the main factors controlling the sedimentary process through the use of textura and grain-size parameters. Based on the spatial drsrribution of these parameters, the fiord inlet system is divided into two energy zones. This energy-based dijferentiation would be mainly determined by the geomorphological characteristics of the area.
