Estratigrafia do perfil norte da unidade de escavação do sítio GO-Ja-02, Serranópolis, Goiás: análise preliminar

Abstract

The archaeological site GO-Ja-02 located in the municipality of Serranópolis, southwest of the state of Goiás, is situated in a sandstone shelter and features a complex stratigraphy. This site serves as a crucial source for understanding the process of occupation of the Brazilian Central Plateau, housing cultural artifacts and human burials that date back up to 12,000 years Before Present (AP). The primary objective is the preliminary analysis of the stratigraphy off the northern profile of the excavation unit, aimed at supporting broader approaches to the site. Field and laboratory activities were conducted, allowing the characterization of the matrix based on variables such as color, grain size, roundness, sphericity, thickness, and shape, which facilitated the identification of six stratigraphic layers. The results reveal an intricate interplay between natural process, such as rainwater runoff and bioturbation, and human occupation, highlighting a homogeneity in terms of grain size, roundness, and sphericity, as well as variations in color. The results underscore the importance of the GO-Ja-02 site, shedding light on the formation processes of the archaeological record.
