Portable X-Ray Fluorescence Spectroscopy for Rapid and Cost-Effective Determination of Elemental Composition of Ground Forage

Frontiers in Plant Science, 2019
The recent development of portable X-ray fluorescence spectrometers (PXRF) has created new avenues for rapid plant elemental concentration determination at reduced cost while avoiding hazardous chemicals. A few studies have indicated the potential use of

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.

Analysis by pXRF of Prehistoric Obsidian Artifacts From Several Sites on Ustica (Italy): Long-Distance Open-Water Distribution From Multiple Island Sources During the Neolithic and Bronze Ages

Open Archaeology, 2020
The small island of Ustica was a regular part of the obsidian distribution network in the central Mediterranean, despite its location more than 50 km north of western Sicily.

Crossing Ceramic Decoration Boundaries: Compositional and Morphological Analyses of the Mortuary Assemblage From Maridíaz (Nariño, Colombia)

Archaeometry, EarlyView.
ABSTRACT This paper examines the interaction of two ware traditions in the Maridíaz mortuary assemblage (Pasto, Nariño, Colombia), a rare, well‐documented cemetery context in which Piartal, Tuza, and hybrid vessels co‐occur. Using portable X‐ray fluorescence (n = 39) and 3D geometric morphometrics (n = 25), we find shared ceramic compositions ...

Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

Archaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...
