The first results of the archaeological research being developed at the interfluve of the Peixe and Araguaia rivers, indicate the possibility to applying geoarchaeological issues to address a number of issues related to the Lago Rico site, on the left bank of the Peixe river. This site features cultural remains in a section of a low slope as well as two other areas. The first in the alluvial terrace by a lagoon and the second in the floodplain, upstream of the first section, evidencing the erosive-depositional behavior of the river in the archaeological site area. The depositional segment, presents evidence of a different environmental context from the current one (an ancient erosive margin), allowing the hypothesis that part of the site may have been eroded transporting cultural remains downstream. To investigate these hypotheses, the use of the issues geoarchaeological is fundamental to identify the cultural remains in the lagoon area and the depositional margin and obtaining information to aid in characterizing the behavior of the river channel and description of stratigraphic profiles.
