Dolomite and Mg Calcite as Mineral Thermometers in Mortar Binders. A High Resolution Raman Spectroscopic Study

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman band characteristics of calcium carbonates from experimentally heated and recarbonated dolomite samples and of carbonate aggregates in a high‐fired gypsum mortar were correlated using high spectral and spatial resolution micro‐Raman. The band parameters of the carbonate minerals correlate to the applied burning temperature, hence allowing a ...

Non‐invasive Analyses of an Etruscan Fibula From Vulci (Italy): The Benefits of a Combination of Micro‐Raman Spectroscopy, 3D Reconstruction Through X‐Ray Microscopy and ED‐XRF With Monte Carlo Simulation

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study analyzed an Etruscan bronze fibula through non‐destructive techniques. The patina and alloy were examined using micro‐Raman spectroscopy and ED‐XRF with Monte Carlo simulations, revealing the formation of corrosion products such as brochantite and sampleite and a binary Cu‐Sn alloy composition.

Raman Spectroscopy of Amphibole Inclusions in Emeralds

open access: yesJournal of Raman Spectroscopy, EarlyView.
Emeralds containing elongated amphibole inclusions from Austria, Russia, Zambia and Zimbabwe were investigated with an optical microscope and Raman spectroscopy. The inclusions have various sizes and shapes; curved inclusions are frequently observed in emeralds from Zimbabwe and rarely in those from Zambia.

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...
