Plots of SiO2 (wt %) versus (a) TiO2, (b) FeO (c) MgO, and (d) CaO for 74220. The glass interiors generally fall within ranges of previous data (Delano, 1986; Shearer & Papike, 1993; Chen et al., 2015), but the new data for 74220 greatly expand the range in major element compositional variations for this sample, particularly for crystallized beads. Vectors for olivine addition (Ol +), removal (Ol −) and ilmenite addition (Ilm+) shown.
