Résumé
"Recent archaeological research demonstrates that the south-central highlands was a region of important sociocultural developments during the Early Horizon (ca. 800-200 BC). One reason for the prominence of this region was the local availability of obsidian, a widely exchanged lithic material. In this paper, we discuss the results of a portable X-ray fluorescence (pXRF) sourcing study of a sample of 26 obsidian artifacts from the site of Pallaucha, an Early Horizon civic ceremonial center located near Vilcashuaman in the Department of Ayacucho, Peru. PXRF analysis demonstrates that the Quispisisa source was the most commonly exploited locality to acquire obsidian at Pallaucha even though other sources were in closer proximity. Our results complement the results of a study of a large sample of obsidian from the nearby, and partially contemporary, civic-ceremonial center of Campanayuq Rumi."
