Electron probe microanalysis data for major elements in clinopyroxene, olivine, amphibole, and glass from lava and tephra of the 2021 Tajogaite eruption on La Palma. Laser ablation ICPMS provides trace element analyses for selected clinopyroxene samples. The dataset was contributed by the British Geological Survey.
Use Cases
- Compare major element concentrations in clinopyroxene, olivine, amphibole, and glass to model magma evolution during the eruption.
- Analyze trace element data from clinopyroxene to identify geochemical signatures of different eruption phases.
- Correlate geochemical variations in lava and tephra samples with physical volcanology observations from the 2021 event.
Strengths
- Data covers multiple mineral phases (clinopyroxene, olivine, amphibole) and volcanic glass, providing a multi-phase geochemical profile.
- Includes both major element (EPMA) and trace element (LAICPMS) analytical techniques for clinopyroxene.
- Focuses on a specific, well-documented volcanic event: the 2021 Tajogaite eruption on La Palma.
Limitations
- Sample size and row count are unknown, limiting statistical power for some analyses.
- Column names and data structure are unspecified, requiring inspection to understand the feature set.
