Iron Compounds in Brazilian Pre-Columbian Pigments Identified by 57Fe Mossbauer Spectroscopy and X-Ray Powder DiffractionApplications of the Mossbauer Effect
AbstractMossbauer spectroscopy and X-ray powder diffraction have been used to identify iron compounds in pre-Columbian pigments, probably used for art decorating, collected from the oldest archaeological site of Early Man presently known in American at Sao Raimundo Nonato, in Northeastern Brazil. The iron compounds were identified as being alpha-Fe203 (haematite) with full Morin transition supressed and small particles of alpha-FeOOH (goethite).
