Documentación, microfotografía y caracterización multianalítica de pigmentos de la Cueva de los Machines, Oaxaca, México

A comprehensive analysis of pigment composition in the Cueva de los Machines, part of Oaxaca's UNESCO-listed Rock Paintings of the Sierra de San Francisco, reveals a rich palette of mineral-based materials used by prehistoric artists. The study employed advanced techniques such as microphotography, photogrammetry, Raman spectroscopy, and X-ray fluorescence to characterize pigments, providing unprecedented insights into the technical sophistication of ancient rock art production. Findings indicate the use of diverse mineral sources, including iron oxides, suggesting complex trade or resource procurement strategies during the region's early human occupation, spanning from the Pleistocene-Holocene transition to the Postclassic period.
