* The ten major oxides (reported in weight percent) are normalized to H2O-free totals of 99.6 wt % (allowing 0.4% for trace oxides and halogens.) Determinations by wavelength-dispersive XRF in USGS laboratory at Lakewood, CO; D.F. Siems, analyst. Precision and accuracy are discussed by Bacon and Druitt (1988) and Baedecker (1987). FeO* is total iron calculated as FeO. "Original total" is the volatile-free sum of the ten oxides, as analyzed, before normalization, with total iron calculated as Fe2O3. LOI, weight loss on ignition at 900C. Cone and sector are given to assist reader in locating sample number on figure 2. *
