EDXRF Raw data 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.本次数据集包含566组地球化学原始数据，对应133件以打制石器、磨制石器为主的地质及考古类黑曜岩制品标本。所有样品均由赛默飞世尔科技（Thermo Fisher Scientific）XL3t系列尼通X射线荧光分析仪（X-Ray Fluorescence XL3t series NITON Analyzer）完成测定，并依托赛默飞™尼通数据传输（NDT™）软件（Thermo Scientific™ Niton Data Transfer (NDT™)）提供技术支持。分析工作先期开展实验阶段以确立最终分析规程：每件黑曜岩样品至少重复3次分析，在尼通分析仪的SOIL或TestAllGeo分析程序模式下，确保计数率达到每秒120次。
