Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

open access: yesJournal of Raman Spectroscopy, EarlyView.
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).

Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

open access: yesJournal of Raman Spectroscopy, EarlyView.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

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

open access: yesJournal of Raman Spectroscopy, EarlyView.
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

open access: yesJournal of Raman Spectroscopy, EarlyView.
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).
