Abstract
Infant teeth with extremely rare colored enamel regions white, blue-gray an d brown, have been analyzed by Particle Induced X-ray Emission (PIXE) and R utherford Backscattering Spectrometry (RBS). The teeth were part of human b eing sacrifices to deities of the Mexica culture, Mexico, corresponding to the Late Post-classic period (1325-1521 A.D.). Comparisons to normal teeth from the same historical period indicate that the colored ones present larg er mean amounts of Mn and Fe, while Zn and Sr do not differ too much. Possi ble inorganic compounds responsible for the different colorations are indic ated. (C) 1999 Elsevier Science B.V. All rights reserved.
