| description |
The first results of portable in situ XRF analysis performed in rock art in the Argentinean Patagonia, with the aim of determine the pigments of the paintings, are presented in this work. Five archaeological sites with rock art in Las Chapas, Chubut, were studied. The paintings are characterized by red monochrome geometric and abstract motifs. As the paintings are very deteriorated or in very thin layers no other technique could be applied to study them before. The results are only indicative and they require additional techniques to determine mineral pigments, however in the well preserved red and yellow paintings, the color is attributed to the presence of minerals with Fe, like hematite or limonite respectively. Additionally, potentially primary sources of black and yellow pigments are given to know for the first time. |

En este trabajo se presentan por primera vez en Patagonia argentina, los estudios realizados in situ con un equipo portátil de fluorescencia de rayos X para identificar la composición pigmentaria de pinturas rupestres. Se estudiaron cinco sitios arqueológicos con manifestaciones rupestres de la localidad Las Chapas (Chubut) que se caracterizan por representar motivos geométricos y abstractos habitualmente monocromáticos. Las pinturas se presentan en ocasiones muy desvaídas y/o con un espesor muy delgado, motivo por el cual, no han podido ser implementados otros análisis a la fecha. Los resultados obtenidos son orientativos y requieren de técnicas complementarias, no obstante, en las pinturas rojas y amarillas bien conservadas se destaca la participación de minerales de Fe como materia pigmentaria que fueron interpretados como hematita e hidróxidos de hierro respectivamente. En la elaboración del color blanco se presume la utilización de yeso debido a la presencia de S y Ca en las lecturas. Complementariamente se dan a conocer potenciales fuentes primaria de materias primas pigmentarias de color negro y amarillo. Este trabalho apresenta pela primeira vez na Patagônia argentina, estudos realizados in situ com equipamentos portáteis de fluorescência de raios X para identificar a composição pigmentar de pinturas rupestres. Foram estudados cinco sítios arqueológicos com pinturas rupestres de Las Chapas (Chubut), caracterizados por motivos geométricos e abstratos, geralmente monocromáticos. As pinturas são às vezes muito desbotadas e/ou com uma espessura muito fina, razão pela qual nenhuma outra análise foi realizada até o momento. Os resultados obtidos são indicativos e requerem técnicas complementares; entretanto, nas pinturas vermelhas e amarelas bem conservadas, destaca-se a participação de minerais de Fe como material pigmentar, que foram interpretados como hidróxidos de ferro e hematita, respectivamente. Na elaboração da cor branca, presume-se o uso do gesso devido à presença de S e Ca nas leituras. Complementarmente, são reveladas potenciais fontes primárias de matérias-primas pigmentares pretas e amarelas. Centro de Estudios Históricos.
