Archaeometric provenance study of marbles from Porphyreon and Chhim (Lebanon) and early Byzantine production specialisation

Archaeometry, Volume 67, Issue 5, Page 1129-1156, October 2025.
Abstract Early Byzantine marble objects from Porphyreon and Chhim (Lebanon) were studied to assess the source of raw materials. In all, 66 artefacts, including elements of liturgical furnishings, architectural elements and daily use objects, were examined using optical, cathodoluminescence and scanning electron microscopy, X‐ray diffraction, and δ13C ...

Tracing the origin of Roman mosaic tiles in Aquileia: Petrographic analysis of specimens from the suburbium

Archaeometry, Volume 67, Issue 5, Page 1247-1266, October 2025.
Abstract This research represents the most extensive characterisation of Roman mosaic tesserae (tiles) from Aquileia, Italy, to date, examining 153 specimens. The study aimed to identify the lithotypes used in mosaics production through a multi‐analytical approach, which included colorimetric analysis, polarised light microscopy and scanning electron ...

Accessory minerals: a provenancing tool for steatite quarries

Archaeometry, Volume 67, Issue 5, Page 1212-1229, October 2025.
Abstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history.

Sulfur Isotope Biogeochemistry Controlled by Sulfate Reduction Activity in Cold Seep Sediments

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Cold seeps are unique deep‐sea ecosystems that play an important role in marine biogeochemical cycles. However, the dynamics and regulation of sulfur isotope biogeochemistry in seep sediments remain unconstrained. We investigated the geochemical characteristics of active seep sites, including the content and stable isotope composition of ...

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 406-421, September 2025.
The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.
