abstract = {We report on the analysis of a red pigment found in a lavish Inca burial from Cerro Esmeralda, Chile, associated with the human sacrifice of two young girls. The outcome shows that the red pigment is mainly cinnabar, with 95% of HgS content. Cinnabar is rarely found in the archaeological record of Chile. Thus, we propose that our results are another line of evidence supporting Iquique's Cerro Esmeralda inhumation as a unique Inca ritual. It was a special lower-elevation capacocha burial, most probably undertaken to politically and symbolically incorporate the coastal people into the Tawantinsuyo Empire.},

abstract = {Micro-Raman spectroscopy was used to analyze and identify pigments and determine the palette of color in wall paintings from four churches of the Colonial Period, in the Bolivian highlands. The ancient churches Santiago de Callapa, Curahuara de Carangas, Nuestra Senora de Copacabana de Andamarca and San Jose de Soracachi were constructed during the 17th and 18th centuries, around the important colonial Ruta de la Plata, between Potosi city and Arica harbor on the Paciic coast of South America. Most pigments used in the wall paintings correspond to inorganic minerals as well as to organic colorants. Fully chlorinated copper phthalocyanine (green), copper phthalocyanine (blue), beta-naphthol (yellow) and benzoimidazolone (red), were identiied in the corresponding colored areas suggesting subsequent recent interventions or restorations. Ground layer materials were also characterized. The present results allow for discussion of the pictorial techniques used in the Andean highland during the colonial period and allow conservators and restorers to make important decisions regarding the type of intervention to perform in the case of these important historical and patrimonial monuments.},

abstract = {Analysis of two archaeological red pigments from two cities in northern Chile, Calama (Calama sample) and Iquique (Iquique sample) are reported in the current work. Scanning electron microscopy and energy dispersive X-ray spectrometry (SEM-EDX), powder X-ray diffraction (XRD) and vibrational spectroscopy (JR and Raman) were used for structural studies. Hematite (alpha-Fe2O3) was the main component of the red color in both pigments. These are the first results reported for both sampled areas, helping thus to clarify) the Calama funeral rites and the raw materials used for Chinchorro mummification in the Iquique region. The characterization of the raw materials provides information for future studies focused on hematite mining processes.},
