Distinguishing Soil Horizons of Alfisols Using MIR, Vis–NIR, and XRF Spectra
European Journal of Soil Science, Volume 77, Issue 3, May–June 2026.ABSTRACT We studied horizonation of 150 Alfisols on a research farm in Wisconsin, USA. Most of these Alfisols had developed in loess covering dense glacial till; common horizons were an Ap over a glossic horizon (E/Bt or Bt/E) over a Bt covering the glacial till (2Bt). In addition to field identification, we distinguished the horizons by combining soil

The potential of obsidian "big data"
UISPP Journal, 2019 Studies of obsidian provenance have been a core component of the archaeological sciences from the mid-1960s onward. With the growing application of portable X-ray Fluorescence Spectrometers (PXRF) in obsidian research, the number of such studies, and the

Open Archaeology, 2017 The introduction of copper-based metals in Sicily appears to have been a particularly late and slow process. A program of pXRF analyses on early metals in Sicily has revealed the use of mostly copper, and a very late introduction of tin.
