The Atlantic Rio Grande do Sul (Brazil) and Uruguay inner continental shelf was used as a natural laboratory to test the relationship between grain-size properties and sedimentary environment. The Pleistocene/Holocene evolution of the region was intensively studied through detailed mapping, sedimentological and stratigraphic research thus offering an excellent opportunity of developing this type of work. Sand and gravel deposits linked with identified stillstands of the Holocene transgression located at 110-120 and 20-30 meters isobath provided elements related to the source, transport and depositional energy level and can be used as a tool for environmental interpretation.
