Cabo Ortegal in northern Spain is the source for this collection of reflected light microscopy images, backscattered electron images, element maps, and laser ablation ICP-MS data for Fe-Ni-Cu sulfide minerals. The data were acquired in 2021 and 2022 from dunite, harzburgite, and pyroxenite samples held at Cardiff University. It was gathered to understand concentrations and mineral forms of precious and semi-metal trace elements in sulfides.
Use Cases
- Classifying sulfide mineral textures and associations based on reflected light microscopy images.
- Mapping elemental distributions and mineral phases using the provided element maps and backscattered electron images.
- Analyzing concentrations of precious and semi-metal trace elements from the laser ablation ICP-MS spectral data.
- Correlating visual petrographic features with quantitative geochemistry for mineralogical studies.
Strengths
- Data includes multiple complementary modalities: images, element maps, and quantitative spectral analysis.
- Acquisition instruments and operating conditions (e.g., 20kV, 4 nA beam current) are specifically documented.
- Samples are from a defined geological location (Cabo Ortegal) and collection (Prof Hazel Prichard's).
Limitations
- Row count and file size are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Description metadata is limited; actual data quality requires manual inspection after download.
Provenance
- Source
- British Geological Survey (BGS)
- Collection Method
- Petrographic assessment and element mapping used a Zeiss Sigma HD Field Emission Gun Analytical Scanning Electron Microscope. Laser-ablation ICPMS analyses used an ESI UP213 laser system coupled to a Thermo iCAPRQ ICP-MS.
- Time Range
- Data acquired during 2021 and 2022.
