| description | The Letreiro do Quinto rock shelter is located in the rural area of the city of Pedro II, Piauí, Brazil. The sandstone walls of the shelter are covered with prehistoric rupestrian paintings, painted in patterns of yellow and light and dark red hues. The chemical-mineralogical characterization of the prehistoric pigments was made with energy dispersive spectroscopy, scanning electron microscopy, energy dispersive X-ray fluorescence and 57Fe transmission Mössbauer spectroscopy at 110 K. Results confirm the occurrence of hematite- and goethite-rich ochres and also that the pigment layers are indeed made of a mixture of clay minerals mixed with iron oxides. |
