Abstract
This work evaluated the elemental composition of decorated pottery pubic covers (tangas) from the Marajoara culture of Marajó Island (at the mouth of the Amazon River, Brazil) using EDXRF technique. The XRF system used in this work consists in a Si(Li) detector from ORTEC, with resolution of 180eV, at 5.9keV, and a mini X-ray tube with Mo anode. The elements identified in the samples were: S, Cl, K, Ca, Ti, Mn, Fe, Cu, Zn, Ga, Rb, Sr, Y, Zr and Pb. Principal components analysis (PCA) was used to evaluated the provenance of the samples.
