The Pace di Siena and its Gems

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1254-1278, November 2025.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.

Sourcing obsidian from prehistoric sites in northwest Romania

Materiale și Cercetări Arheologice, 2018
Portable X‐ ray Fluorescence Spectroscopy (pXRF) was used to reveal the chemical signatures of 75 obsidian artefacts from seven sites in the Satu Mare region, ranging in age from Early Neolithic (late Starčevo‐ Criș culture) to Late Copper Age.

The Holocene sedimentary record of Mittie Glacier dynamics in Smith Bay, Ellesmere Island (eastern Canadian Arctic Archipelago)

Journal of Quaternary Science, Volume 40, Issue 7, Page 1191-1211, October 2025.
ABSTRACT The physical, sedimentological, mineralogical, and elemental geochemical properties of sediment cores collected in Smith Bay (22BC and 01PC), and near the front of Mittie Glacier (23BC and 01GC), were used to reconstruct glacial sediment discharge and trace the long‐term composition and provenance of detrital sediments for the northeastern ...

Advancing Leaf Nutritional Characterization of Blueberry Varieties Adapted to Warm Climates Enhanced by Proximal Sensing

AgriEngineering
Blueberries offer multiple health benefits, and their cultivation has expanded to warm tropical regions. However, references for foliar nutritional content are lacking in the literature.

Determining the impact of elemental composition on the long‐term survival of vegetable‐tanned leather in archaeological environments

Archaeometry, Volume 67, Issue 5, Page 1394-1411, October 2025.
Abstract This research paper investigated whether elemental analysis can differentiate leather manufacturing from soil contamination and whether soil hydrology and elemental composition impact degradation of leather. Portable X‐ray fluorescence (pXRF) is a quick method for monitoring large‐scale changes and groupings of aggregate inorganic elemental ...

Distinguishing Spiennes and Lanaye Flints Using Portable ED‐XRF to Trace Neolithic Exchange Networks in the Rhine‐Meuse Delta

X-Ray Spectrometry, Volume 54, Issue 5, Page 478-487, September/October 2025.
ABSTRACT Flint, or chert, sources in the Rhine‐Meuse delta are generally distinguished based on macroscopic characteristics such as fossil inclusions, colour variations, and translucency. Previous studies on chemical characterisations of flint sources proved challenging due to the variation and overlap between different sources. Energy Dispersive X‐ray

Prediction of Foliar Nutrient Contents and Differentiation of Scion/Rootstock Combinations in Citrus via X-Ray Fluorescence Spectrometry

AgriEngineering
Citriculture has worldwide importance, and monitoring the nutritional status of plants through leaf analysis is essential. Recently, proximal sensing has supported this process, although there is a lack of studies conducted specifically for citrus.

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

Using pXRF for the Analysis of Ancient Pottery – An Expert Workshop in Berlin 2014

, 2020
The aim of the second workshop on the use of portable energy-dispersive X-ray fluorescence (pXRF) organized by the Cluster of Excellence TOPOI was to exchange experiences and discuss the basic requirements for the use of pXRF as a tool for chemical analysis of archaeological ceramics.
