  1. n: number of analyses included in average, b.d.l.: below detection limits, 0.02 wt% Ca, 0.03% Na, 0.02% P, 0.08% Cu, 0.06% Cr, 0.06% Ni; SEM-EDS detection limit ~0.1 wt%. Uncertainty given in parentheses represents one standard deviation from the mean based on: counting statistics (for olivine); all analyses (for spinel and glass), [e.g., 50.3 (13) = 50.3 (1.3) = 50.3 +/- 1.3]. aS# refers to a point analysis of olivine, where the # corresponds to a location specified in Figures 2c or 2d. bForsterite content (“Fo”) calculated as average of [Mg]/2 and 1 - [Fe]/2, where [Mg], [Fe] are atomic ratios of Mg and Fe, respectively, normalized to 3 cations. cLocation refers to Figure 2b. dAll Fe in glass compositions considered as FeO. eFe2O3 content calculated by charge balancing on the basis of 4 Oxygen atoms. fSp-Mg analyzed by SEM-EDS (unnormalized).
