Interactions between sedimentary evolution and prehistoric human occupation in the south-central coast of Santa Catarina, Brazil

Since the beginning of the human occupation in click here the south-central coast of Santa Catarina State, in Brazil, the articulation between natural and anthropic processes modeled a strongly domesticated landscape, shaped by the massive construction of shell mounds of monumental dimensions and millenarian permanence.In the coastal plain between Passagem da Barra (Laguna District) and Figueirinha Lake (Jaguaruna District), 76 sambaquis were mapped, 48 of which have been dated.Systematic site surveys and radiocarbon datings allowed identifying patterns of spatial distribution in sambaquis according to the sedimentary context at the time of construction, stratigraphy and age.Based on these criteria, the following groups were recognized: five geological-geomorphological contexts of location; three stratigraphic here patterns; and four phases of sambaqui occupation in the area, based on site number and type of constructive pattern.The model for sedimentary evolution and time-space distribution of sambaquis shows that sites were built in already emerged areas and that inland sites, away from the lagoons, may have not be preserved or they are not exposed due to the continuous sedimentary filling that characterized this region after the maximum Holocene transgression.

The crossing of data, here proposed, shows the importance of integral approaches between archaeology and geosciences for the study of landscape evolution.
