Major and trace element characterization and correlation of the Sentinel Butte Ash/Bentonite (Paleocene), McKenzie County, North Dakota
… bentonites, and the ash, on the basis of their elemental concentrations. Factor analysis was used to determine which trace elements had the lowest variability associated with them, and to use those elements as a geochemical fingerprint. </p><p> The geographic and geological variability of the …

A study of obsidian in prehistoric central and Eastern Europe, and it's trace element characterization. An analytically-based study of archaeological obsidian in Central and Eastern Europe, an investigation of obsidian sources in this area, and the characterization of these obsidians using neutron activation analysis.
… analysed by neutron activation analysis for 15 trace and two major elements. The trace elements used included those which are geochemically likely to show the greatest variation between different obsidian sources, and which are not badly affected by devitrification and hydration of the obsidian, …
