Resumo
In this work, 22 clay samples near Hatahara and Açutuba archaeological sites, and 135 ceramic samples were
analyzed by means of Instrumental Neutron Activation Analysis. INAA is the most suitable technique because it
does not require mineralization of samples and has high sensitivity, accuracy and precision. The samples were
irradiated in IEA-R1 reactor at IPEN-CNEN-SP at thermal neutron flux of 8,92x10

during one hour.
The elementary concentration results were studied using multivariate statistical methods. The compositions
group classification was done through cluster analysis and the similarity/dissimilarity among the samples was
studied by means of discriminant analysis.
