| dc.description.abstract | Chemical characterization of ceramic fragments is of great importance in archeology, due to the fact that relevant aspects of the ancient people can be clarified. Ceramics basically consist of a paste of clay with added temper. The presence of the temper can modify the chemical composition of the ceramic fragments, altering their characterization due to temper being a modifier of the natural composition of the clay used. Therefore, it is necessary to study its effect in the concentration of the inorganic elements in the ceramics. In this work, 161 Marajoara ceramic fragments were analyzed by instrumental neutron activation analysis (INAA) to determine the As, Sa, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Na, Nd Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn concentrations, with the purpose of studying the dilution effect provoked by temper. The analytical method is indicated for this kind of study because it presents high sensitivity, accuracy and precision in the determination of chemical elements to the level of trace and ultra trace elements, essential characteristics in the study of small concentration variations provoked by temper. The dilution factor was studied using a modified Mahalanobis filter. The data were interpreted through discriminant analysis. | |
