Full‐field X‐ray fluorescence imaging using a Fresnel zone plate as a coded aperture: optimized reconstruction algorithm and first trial of hyperspectral XANES mapping

Journal of Synchrotron Radiation, EarlyView.
The full‐field X‐ray fluorescence imaging method, where a Fresnel zone plate is employed as a coded aperture, was tested for the first time at a beamline, and its corresponding reconstruction code was optimized. It was also employed to perform, also for the first time using full‐field and fluorescence modes, hyperspectral XANES mapping.This study ...

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
