Raman spectroscopic identification of cookeite in the crystal-rich inclusions in spodumene from the Jiajika lithium pegmatite deposit, China, and its geological implications

, 2020
. Cookeite usually occurs as a late alteration product in lithium–cesium–tantalum-type granitic pegmatite. Consequently, cookeite-bearing crystal-rich inclusions (CIs) in pegmatite are considered to be of secondary origin, which constrains our ...

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1378-1385, November 2025.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).

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

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1235-1253, November 2025.
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 ...

Study on the Types, and Metallogenic and Diagenetic Environment of Tourmaline from the Zhongzuo Pegmatite Veins in Quyang County, Hebei Province

Yankuang ceshi, 2017
Tourmaline is an efficient tracer during diagenesis and metallogenesis. Chemical composition of tourmaline can not only be used to give information about environment of diagenesis and metallogenesis, but can also be useful in prospecting.

Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1404-1417, November 2025.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1418-1433, November 2025.
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).
