EDXRF Raw data of Sonora obsidian

566 geochemical raw data, corresponding to 133 specimens of geological and archaeological obsidian artifacts mostly, including flaked and ground stone, were determined by an X-Ray Fluorescence XL3t series NITON Analyzer from Thermo Fisher Scientific with support of the software Thermo Scientific™ Niton Data Transfer (NDT™). The analysis had an experimental stage to generate a final analytical protocol, based in a repetition of at least 3 analyzes per obsidian sample, procuring 120 counts per second, under the SOIL or TestAllGeo condition programs of Niton. Table 1. Geochemical selected data of geological and archaeological obsidian specimens analyzed from Sonora, Mexico. See description and localization of the sites and regions in [1]. Concentrations are in mg/kg. Confidence limit (± CL1-α = 95) are displayed with a 95% probability (2-Tail Alpha X mean). The empty cells (NA) correspond to elements that were not analyzed or below to the detection limit of the instrument. The table only includes calculations of the confidence limit for samples with three or more repetitions. Figure 1.
