“…Ochres have been studied mainly in order to characterize and produce different industrial pigments (Buxbaum and Printzen 1993; Marshall et al 2005; Elias et al 2006; Cornell and Schwertmann 2006). In geoarchaeology, their study has been focused on the physicochemical characterization of different pigments used in cave paintings (e.g., Clottes et al 1990; Baffier et al 1999; Navarro Gascón 2003; Navarro Gascón and Gómez González 2003; Garate et al 2004; Ospitali et al 2006; Vignaud et al 2006) and ochre pieces recovered during archaeological excavations (Couraud 1983, 1984/5, 1991; Baffier et al 1999), or in experimental archaeology works, in order to understand the know‐how of prehistoric artists (Couraud 1988; Weinstein‐Evron and Ilani 1994; Pomiès et al 1999).…”

The Origin and Geochemical Characterization of Red Ochres From the Tito Bustillo and Monte Castillo Caves (Northern Spain)*

Ochres were the most common source materials for pigments used in Palaeolithic rock art paintings. This work analyses the petrographic and geochemical signatures of different ochre samples from outcrops inside Tito Bustillo Cave and the Monte Castillo Caves using the most common techniques (petrography, XRD, SEM–EDS and ICP–MS) in archaeological pigment characterization studies. The results obtained permit the identification and characterization of the different source ochre types and, furthermore, allow the establishment of mineralogical and geochemical proxies for the study of questions related to ochre characterization, formation processes and provenance.

Ochres from rituals of prehistoric human funerals at the Toca do Enoque site, Piauí, Brazil

The archaeological site known as Toca do Enoque (geographical coordinates, 09 • 14 65.3 S 43 • 55 62.5 W) is a rock shelter located in the Serra das Andorinhas (Serra das Confusões National Park), rural area of the city of Guaribas, state of Piauí, Brazil. Several rupestrian paintings (anthropomorphic and zoomorphic motifs along with some pure graphisms), predominantly in red, are found on the sandstone walls. Charcoals, lithic materials, necklaces with teeth, animal bones, gastropod shells, ochres and human skeletons (dated from 6,220 ± 40 to 6,610 ± 40 years before present, BP) were identified in recent excavations in this shelter. Red and yellow ochre samples were collected from prehistoric funeral structures and L. C. Duarte Cavalcante et al. Fig. 1 Map of the Parque Nacional Serra das Confusões and Toca do Enoque site analyzed with powder X-ray diffractometry, Fourier-transform infrared spectroscopy and 57 Fe transmission Mössbauer spectroscopy at 298 K and 80 K. Mössbauer data indicate that the red ochre do contain predominantly hematite (α-Fe 2 O 3 ) whereas goethite (α-FeOOH) is the major mineral in the yellow ochre.

O sítio de arte rupestre Poções está localizado na área rural da cidade de Gentio do Ouro, Bahia, Brasil. As paredes de arenito estão cobertas de grafismos geométricos, havendo poucos motivos antropomórficos, zoomórficos muito esquematizados e escassos fitomorfos. A caracterização químico-mineralógica do pigmento de uma pintura alaranjada foi feita em aboratório usando espectroscopia de energia dispersiva, espectroscopia de absorção no infravermelho com transformadade Fourier, difratometria de raios-X do pó, espectroscopia Mössbauer de 57Fe a 298 K e 110 K, espectroscopia de absorção molecular UV-Vis e reação de complexação com tiocianato. Os resultados revelaram a presença de goethita e hematita com pequeno tamanho de partícula, bem como de outros compostos oxídicos (super)paramagnéticos.
