Arianna's Palette: A Diagnostic Study of the Painting Walls of the Domus of Arianna in Pompeii

open access: yesArchaeometry, EarlyView.
ABSTRACT The House of Arianna, also known as the House of Colored Capitals, represents, with its 1700 m2 of floor space, one of the most majestic examples of a residence within the Pompeii archaeological site. The research developed within the project “Cultural Heritage Active Innovation for Sustainable Society—CHANGES” reports the outcomes of the ...

On Sourcing Stonehenge Sarsen Stone #58: A Response to Nash and Ciborowski's Comments

open access: yesArchaeometry, Volume 68, Issue 1, Page 48-50, February 2026.
ABSTRACT This is a brief response to Nash and Ciborowski's comments in 2025 on our 2024 paper, which focused on the reinterpretation of geochemical data for Stonehenge stone #58 published by Nash et al. in 2020. We address the problems they perceived in our use of absolute elemental concentrations, our selection of discriminating elements, and single ...

The Soil Erosion Paradox Re‐Examined: Alluviation and Land Use History in a Small British Lowland River Catchment in the Late Holocene

open access: yesGeoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Modern studies show that soil erosion results in a loss of ecosystem function, particularly fertility, and is a cause of declining agricultural yields. However, despite the well‐attested high rates of soil erosion across Roman and medieval Europe there appears to have been little or no soil‐associated decline in agricultural production—the ...

Elemental concentration via portable x-ray fluorescence spectrometry: Assessing the impact of water content

open access: yesCiência e Agrotecnologia
Portable X-ray fluorescence (pXRF) analysis can be considered one of the main recent advances for chemical characterization of earth materials. The water content of the samples can affect the pXRF performance.

The Application of Portable X-ray Fluorescence (pXRF) for Elemental Analysis of Sediment Samples in the Laboratory and Its Influencing Factors

open access: yesMinerals, 2023
Several techniques, such as chemical methods and inductively coupled plasma mass spectrometry (ICP-MS), are available to accurately determine element content. However, they are time-consuming, labor-intensive, or expensive.

A Return to Chalosse Cherts: An Integrated Approach Based on Field Survey, Petrography and Geochemical Analysis to Understand a Palaeolithic Tracer

open access: yesGeoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT The Pyrenees have been considered a natural barrier for prehistoric populations. However, in recent years, Palaeolithic research has established connections between the two sides through the analysis of cherts. Among others, the presence of Chalosse cherts in sites on the southern slopes of the Pyrenees has proven the mobility of objects and ...

The mineral and isotopic signatures of glacially eroded sediments exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich events H0 to H4

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.
ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,

Chemostratigraphy in southern Ontario by pXRF spectrometry

open access: yes, 2017
For groundwater studies, the collection of sediment geochemistry is often beyond the scope, and budget of many programs, and is generally not included as part of routine data collection. Portable x-ray fluorescence spectrometer (pXRF) has proven to be a successful tool to characterize the chemostratigraphy of glacial derived materials collected from ...
