A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Late Iron Age and Early Roman Brooches From the Lower Rhine Area: Provenance of the Metal Supply Traced Through Lead Isotopes

Archaeometry, EarlyView.
ABSTRACT Geochemical analysis of five brooch types from the Lower Rhine area dated to the last century bc and first century ad is used to constrain resource use, exchange and mobility. Lead isotope ratios demonstrate an Iberian provenance for copper in bronze Late Iron Age brooches.

Proximal Sensing and Digital Terrain Models Applied to Digital Soil Mapping and Modeling of Brazilian Latosols (Oxisols)

Remote Sensing, 2016
Digital terrain models (DTM) have been used in soil mapping worldwide. When using such models, improved predictions are often attained with the input of extra variables provided by the use of proximal sensors, such as magnetometers and portable X-ray ...

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Uranium, thorium, and potassium analyses using pXRF spectrometry

, 2021
The application of portable XRF spectrometry (pXRF) for determining concentrations of uranium (U), thorium (Th) and potassium (K) was evaluated using a combination of 12 Certified Reference Materials, 17 Standard Reference Materials, and 25 rock samples collected from areas of known U occurrences or mineralization. Samples were analysed by pXRF in Soil,
