Analytical method: XRF
| Technique | XRF |
|---|---|
| Material | WHOLE ROCK |
| Mineral | none |
| Comment | Major-oxide contents in weight percent, normalized to volatile-free totals of 99.6% (allowing 0.4% for trace oxides and halogens), determined by wavelength-dispersive x-ray-fluorescence analysis in the U.S. Geological Survey laboratory at Lakewood, Colorado; principal analyst D.F. Siems. Precision and accuracy were discussed by Baedecker (1987) and Bacon and Druitt (1988). FeO* is total Fe calculated as FeO. LOI is weight loss on ignition at 900oC. |
