* Major-oxides contents in weight percent, normalized to H2O-free totals of 99.6 weight percent (allowing 0.4 weight percent for trace oxides and halogens); determinations by wavelength-dispersive XRF in USGS laboratory at Lakewood CO; D.F. Siems, analyst. Rb, Sr, and Zr (in parts per million) determined by energy-dispersive XRF by D.F. Siems. Precision and accuracy are discussed by Bacon and Druitt (1988). FeO* is total iron calculated as FeO. "Original total" is the volatile-free sum of the 10 oxides, as analyzed, before normalization, with total iron calculated as Fe2O3. LOI= weight loss on ignition at 900C). *
