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 ...

Perspective on glass properties influencing perlite expansion and strength

Journal of the American Ceramic Society, Volume 108, Issue 10, October 2025.
Abstract Perlite, a naturally occurring volcanic glass, expands upon rapid heating due to internal steam pressure, forming a lightweight, foam‐like porous structure with applications in construction, filtration, and catalysis. Given its industrial significance, the next generation of expanded perlite aims to achieve an optimal balance of lightweight ...

Tectonothermal Evolution of the NW Wyoming Province: Insights From Coupled Garnet Lu‐Hf and Sm‐Nd Geochronology

Journal of Metamorphic Geology, Volume 43, Issue 8, Page 839-862, October 2025.
ABSTRACT Understanding how Paleoproterozoic orogenic processes shaped the assembly of Laurentia remains a critical puzzle in deciphering Earth's ancient tectonic history. To address this challenge, the Montana metasedimentary terrane in the northwest Wyoming Province, which preserves a complex record of multiple metamorphic episodes, provides a unique ...

Trace elements and melt inclusion in zircon within the Qunji porphyry Cu deposit: Application to the metallogenic potential of the reduced magma-hydrothermal system

Open Geosciences
The Qunji porphyry copper (Cu) deposit, located within the Awulale metallogenic belt (AMB) in the western Tianshan orogenic belt, exhibits distinct geochemical and mineralogical characteristics that have not been fully understood.
