Resumen:
Pre-Columbian cultures
iconography present in the Oyola Caves, in the northwestern Argentine province
of Catamarca, were investigated by an interdisciplinary group. The
investigation of the pictographs and petroglyphs included photographic surveys,
archaeological analysis, plastic analysis, production of visual art, and
chemical analysis to determine the composition of pigments and binders. The
motifs represented include camelids, jaguars, human bodies, snakes, and
geometric designs. The dominant color is white in various degrees of saturation
and brightness, although drawings in red, orange, and black were also found.
Small samples of the paintings were extracted and analyzed by scanning electron
microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and microscopic
Fourier transform infrared spectroscopy. The chemical composition
of the different samples, as well as the spacial disposition of the paintings,
suggest a diachronic development for the rock art in the Oyola Caves.
