Artigo IPEN-doc 13431 The archaeometry study of the chemical and mineral composition of pattery from Brazils's northeast2008 - SANTOS, J.O.; MUNITA, C.S.; TOYOTA, R.G.; VERGNE, C.; SILVA, R.S.; OLIVEIRA, P.M.S.In this study, chemical and mineralogical analyses were performed on ceramics and clay samples from Barracão archaeological site located in Baixo São Francisco River. The chemical and mineral analysis was performed by INAA and by means differential scanning calorimetry (DSC). The data set was studied by means of cluster analysis and discriminant analysis. The results showed that the raw material used in ceramics is not local. By using DSC it was possible to discover that the principal minerals in the samples are quartz, feldspars, mica and kaolinite. The existence of kaolinite denotes that the firing temperature of the pottery analyzed was lower than 500 °C. The results obtained in this study, in association with archaeological information, allowed for the identification of the ceramic groups relative to the ceramists occupations at Xingó area.Artigo IPEN-doc 14079 The archaeometry study of the chemical and mineral composition of pottery from Brasil's Northeast2009 - SANTOS, J.O.; MUNITA, C.S.; TOYOTA, R.G.; VERGNE, C.; SILVA, R.S.; OLIVEIRA, P.M.S.
