Argon data for: Elemental, isotopic, and geochronological variability in Mogollon-Datil Volcanic Province, New Mexico

This dataset accompanies publication 'Elemental, isotopic, and geochronological variability in Mogollon-Datil Volcanic Province archaeological obsidian, Southwestern New Mexico: Solving issues of inter-source discrimination', published in Geoarchaeology (https://dx.doi.org/10.1002/gea.21672), which studied the ability of isotopic and argon geochronologic analyses to discriminate between archaeological obsidian sources in the Mogollon-Datil volcanic province.
