- Abstract : In this paper we discuss the use of mineral pigments recovered in stratigraphic position from three excavated archaeological sites (Traful Lake area, Argentina) with the aim of providing information on selection and frequency of use of these raw materials. In this region, human occupation has been recorded since 4000 BP. In order to identify the chromophoric minerals, we applied wavelength dispersive X-ray fluorescence spectrometry, Raman spectroscopy, and X-ray diffraction techniques. Green, red, yellow ochre, and white pigments dated between 3490 and 590 BP were analyzed. The results show that different analytical techniques provide complementary information in order to identify the pigments. Green, red, and yellow samples are related to iron-based compounds. The green pigments can be associated with celadonite and the others with hematite. White samples revealed the presence of hydroxyapatite. Black dots, identified as carbon, were observed in several samples. Red pigments are always predominant, and their relative abundance increases in recent strata. Results are discussed in light of the context and previous reports of chroniclers.

Abstract : En este trabajo se discute el uso de pigmentos minerales recuperados en posición estratigráfica durante la excavación de tres sitios arqueológicos en el área del Lago Traful (provincia de Neuquén, Argentina) con el objeto de proveer información sobre la selección y frecuencia de uso de estas materias primas. En esta región las ocupaciones humanas presentan una cronología a partir de 4-000 años aP. Para la identificación de minerales cromóforos se aplicaron las técnicas de fluorescencia de rayos X, espectroscopia Raman y difracción de rayos X. Se seleccionaron muestras de color verde, rojo, amarillo ocre y blanco datadas entre 3490 y 590 aP. Los resultados muestran la complementariedad de las técnicas para el análisis y la identificación de pigmentos. Las muestras verdes, rojas y amarillas están relacionadas con compuestos basados en hierro. Las verdes pueden asociarse con celadonita y las restantes con hematita; las blancas revelaron la presencia de hidroxiapatita. En varias muestras se observaron también puntos negros identificados como carbón. Los pigmentos rojos son predominantes y su abundancia relativa aumenta en los estratos recientes. Los resultados se discuten a la luz del contexto arqueológico y de los reportes previos de cronistas. … (more)
