For each unit, these data derived from electron microprobe analysis include major-element analyses for glass, amphibole, plagioclase, orthopyroxene, clinopyroxene, Fe-Ti oxides, and, where present, olivine.  Whole-rock major and trace element concentrations for each unit were determined by X-ray fluorescence. These data support detailed petrologic analysis of each Pacheco stage unit presented elsewhere.
