EDXRF Raw data of Sonora obsidian
Description
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.
