| Abstract: | 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. |
