| Abstract: | Chemical characterization reveals intra‐source variation in obsidian from the Paredón source area in Puebla and Hidalgo, Mexico. Two chemical sub‐sources of obsidian from Paredón are spatially discrete and cannot be distinguished by visual characteristics. To facilitate future investigations of the prehistoric exploitation of these sub‐sources, an inter‐laboratory comparison of elemental concentrations is presented based on neutron activation analysis and several XRF instruments. |
