DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.
1393: Major-element chemical analyses of eruptive products, Novarupta 1912
* The 10 major oxides (reported in weight percent) are normalized to H2O-free totals of 99.6 weight percent (allowing 0.4 wt % for trace oxides and halogens); determinations by wavelength-dispersive x-ray fluorescence in US Geological Survey laboratory at Lakewood, CO; supervised by JE Taggart. Precision and accuracy are discussed by Baedecker (1987) and 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 is weight loss on ignition at 900C. *1403: Trace-element chemical analyses of eruptive products, Novarupta 1912
* Determinations (in ppm) by energy-dispersive x-ray fluorescence in U.S. Geological Survey laboratory at Lakewood, CO; D.F. Siems, analyst. Precision and accuracy are discussed by Baedecker (1987) and Bacon and Druitt (1988). Additional data are given by Turner and others (2010). *1413: Trace-element analyses of 1912 eruptive products by Instrumental neutron activation analysis (INAA).
