    Determination of Elemental Composition of NBS 278 and NBS 688 Via Neutron Activation and X-Ray Fluorescence (1985)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Data on NBS Standard Reference Materials 278 (Obsidian) and 688 (Basalt) are presented. Ten major elements, 24 trace elements, iron oxides, and water content were determined using X-ray fluorescence, instrumental thermal neutron activation analysis, delayed neutron assay, spectrophotometry, and coulometry. Good agreement between X-ray fluorescence and neutron activation, and with NBS certified values or recent literature consensus values was obtained.

    Elemental Concentrations in Japanese Silicate Rock Standards JA-1, JR-1 and JB-2 (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Geostandards and geoanalytical research 9 (1985), S. 0

    Topics: Geosciences
    Notes: Data on three Japanese geochemical reference samples (JR-1, JA-1, and JB-2) are presented. Ten major and thirty-five trace element concentrations were determined using x-ray fluorescence, instrumental thermal neutron activation, thermal neutron capture prompt gamma-ray spectrometry, delayed neutron assay, automated thermal neutron activation analysis, inductively coupled plasma emission, atomic absorption, and ion selective electrode. Good agreement between the various methods and with recent literature values were obtained using error weighted mean concentrations for the samples.

    Analyse des Standards de L'U.S.G.S. : GXR-1 a GXR-6 par Activation Neutronique et Fluorescence X (1988)

    Notes: Six roches standards de I'USGS : GXR-1 à GXR-6 ont été analysées par activation neutronique instrumentale (INAA) pour le dosage de 17 éléments traces et par fluorescence X (XRF) pour les autres éléments difficiles à doser par activation neutronique. Les travaux précédemment publiés par Gladney et al. ont été pris comme référence en particulier les valeurs recommandées (R.V.) qui sont généralement en bon accord avec nos résultats. Quelques remarques et corrections sont proposées pour expliquer certaines disparités.Six United States Geological Survey's (USGS) Geochemical Exploration References Samples (GXR) have been analyzed by instrumental neutron activation analysis (INAA) for the determination of seventeen trace elements and by X-ray fluorescence spectrometry (XRFS) for other trace elements difficult to determine by INAA. Our results compare favourably with the values recommended by E.S. Gladney et al. Some suggestions and corrections are proposed to explain some discrepancies.
