* Note. n = total number of glass shards analyzed for each tephra sample. Average and estimated error to one standard deviation from the mean shown for each sample. Analyses normalized to a water-free basis. H2O calculated by difference from analytical total. Total iron oxide expressed as Fe2O3, Moose Creek samples from this study: Eva Creek from Muhs et al. (2001). See Beget et al. (1991) for details of analytical conditions, standards, and instrumentation. *
