“…A lot of analytical methods are widely applied nowadays for classifying the origin of archaeological pottery based on their chemical composition, among them particle induced X-ray emission (PIXE) and X-ray fluorescence analysis (Bakraji et al, 2011;Centeno et al, 2012;Roumie et al, 2010;Padilla et al, 2006;Attaelmanan and Mouton, 2014) and neutron activation analysis (NAA) (Sayre Edwared and Dodson, 1957;Bakraji, 2005;Dasari et al, 2013;Vaughn et al, 2006), as these methods permit the determination of multi-elements simultaneously with high sensitivity, accuracy and precision. The statistical treatment of the elemental concentration helps to determine similarities and correlations between the analyzed pottery fragments, and then classify the pottery sherds into groups.…”
