Resumo
Chemical studies of the ceramics are based on the assumption that
ceramic produced from a specific clay will show a similar chemical
composition and that its composition will be distinguished from that of
ceramics produced from a different clay. It is common to determine the
chemical composition of ceramic using techniques such as neutron
activation analysis, inductively coupled plasma spectroscopy, x-ray
fluorescence analysis. In this work 74 ceramics fragments and 1 clay
from three archaeological sites (São José 26, Saco da Onça 24 and
Curituba: 24) located in the Brazilian Northeast were analyzed using
INAA to determine the concentration of 24 chemical elements. The results
were interpreted by mean of Archaeostatistics techniques, such as Linear Discriminant Analysis and principal components, which was
utilized to facilitate identification of compositional groups. The
Mahalanobis distance was applied for detecting outliers and Wilks’s
lambda provided the critical values. It was obtained that samples from
São José and Curituba are constitute of ceramic pastes different, while
samples from Saco da Onça Site overlap the pottery samples from São
José and Curituba Sites.
