dc.descriptionThis study characterizes the Fazenda Campos Novos (FCN) Sambaqui, a prehistoric shell mound site in Cabo Frio, Brazil. By analyzing the physical, geochemical, and paleoenvironmental aspects of the sambaqui, we aim to understand the environmental conditions associated with the sediments within the shell midden. Methods employed included sediment grain size analysis, X-ray fluorescence, wet chemical characterization, magnetic susceptibility analysis, and radiocarbon dating to provide chronological context. Granulometric data revealed a predominantly sandy loam texture and high magnetic susceptibility values, indicative of human-induced heating events. Chemical analyses revealed elevated levels of organic matter, phosphorus, strontium, and other elements, suggesting significant anthropic influence and resource utilization by prehistoric inhabitants. The presence of marine shells and sandy sediments indicates a coastal depositional environment. Radiocarbon dating placed the sambaqui’s age between 3230 and 3350 years BP, aligning with other regional archaeological sites. Paleoenvironmental reconstructions suggest that the FCN Sambaqui formed during a Holocene marine transgression. These findings enhance our understanding of the cultural practices, environmental conditions, and human-environment interactions associated with the FCN Sambaqui, providing a valuable record of prehistoric life and informing future research on coastal archaeology and paleoenvironmental studies.
