There is no evidence of urban civilization in Brazilian prehistory; most inhabitants lived in tribal groupings, probably with regional economic integration among several independent tribes. There is little evidence of seasonal migrations between the coast and the inland of southern Brazil. Some specialized horticulturists competed among themselves but other groups lived more isolated and probably peacefully, in the upper interfluvial regions. Chemical analysis of artifacts is a means of documenting traffic in particular materials and intraregional production and distribution, development of craft specialization and typological refinement among other issues. In this study we tested some possibilities in two different cultural contexts using the parametric k0 neutron activation analysis technique, which allowed the determination of elements: Al, As, Au, Ce, Cl, Co, Cr, Cs, Cu, Fe, Ga, K, La, Na, Rb, Sc, Ta, Ti, V and Zn.
