The potteries’ chemical fingerprints from Ijuí River, Ibicuí Mirim River, Vacacaí Mirim River and Jacuí River were identified. Interactions between sites from the Jacuí River, Vacacaí Mirim River and Ibicui Mirim River could have occurred because some samples from these sites are overlapping in a principal component analysis (PCA) graphic. The pottery provenance could be the same.785-790openAccessbrazilsample preparationarchaeological sitesx-ray fluorescence analysiscultural objectsceramicsArtigo de periódico43010.1590/S0100-40422007000400006https://orcid.org/0000-0002-6745-8185
