1	XRF-WD	191	"XRF analyses were performed using the Phillips PW2400 wavelength dispersive X-ray Spectrometer at U.C. Berkeley on powdered samples fused with lithium tetraborate flux.  Standards were several natural lavas, including U.S.G.S. standards. Average uncertainties based on replicate analyses are equal to the following percentage of the amounts present: SiO2 (0.08%), TiO2 (0.22%), Al2O3 (0.15%), FeOt (0.08%), MnO (0.66%), MgO (0.24%), CaO (0.18%), Na2O (0.34%), K2O (0.30%), and P2O5 (0.58%).  XRF major and trace element data has been previously published for most samples (c.f.
