New challenges in the study of lithic raw materials in central Italy at the dawn of metal working societies: La Pietra and other radiolarite quarry-workshops in Tuscany

Journal of Lithic Studies, 2016
In central-southern Tuscany radiolarite has been used as a lithic raw material throughout prehistory. During the Copper Age it was selected for the local production of leaf-shaped artefacts. In the area considered, the Copper Age record is almost totally

A ‘Roman Brass’ Age: a transformation in copper-alloy composition in Estonia and northern Latvia during the Roman Iron Age, identified by pXRF

Estonian Journal of Archaeology, 2023
Brass quickly overtook bronze as the dominant copper alloy across vast areas of the Roman world and beyond during the 1st century BC. It has also been established that the quality of this brass changed over time.

Correcting correlation quality of portable X-ray fluorescence to better map heavy metal contamination by spatial co-kriging interpolation

Ecotoxicology and Environmental Safety
High-precision mapping based on portable X-ray fluorescence (PXRF) data is currently being studied extensively; however, owing to poor correlation with soil metal concentration, the original PXRF data directly used for co-kriging interpolation (CKI ...
