Resumen
This paper analyzes the mass fractions of Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Nd, Rb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn
determined from sixty sediment samples obtained from the Lapa Grande de Taquara??u archaeological site using instrumental
neutron activation analysis, INAA. The archaeological site is located in the municipality of Jaboticatubas, about 60 km from
Belo Horizonte, Minas Gerais State, Brazil. The dataset was explored by means of cluster analysis, principal component
analysis and discriminant analysis. The study showed three different compositional groups related to anthropogenic sediment,
fluvial system and oxisols, respectively. The crystalline structure of each group were studied using X-ray diffraction, XRD.
