Experimental and observational data on plagioclase crystals from Mount St Helens volcano. The dataset includes textural measurements and major and trace element geochemistry for both synthesized and natural phenocrysts. It was contributed by the British Geological Survey.
Use Cases
- Model magma chamber processes by analyzing **major element geochemical data for plagioclase and glass** from crystallization-resorption experiments.
- Characterize volcanic crystal populations using **textural data for plagioclase phenocrysts** from Mount St. Helens samples.
- Investigate geochemical evolution by comparing **trace element geochemical data for plagioclase phenocrysts** with experimental glass compositions.
- Assess eruptibility conditions through integrated analysis of **textural data** and **major element** compositions from experimental runs.
Strengths
- Data covers both experimentally synthesized materials and natural samples from the specific Mount St Helens volcano.
- Includes multiple analytical dimensions: textural measurements, major element chemistry, and trace element chemistry.
Limitations
- The sample size and number of data rows are unknown, limiting statistical power assessments.
- Data scope is focused exclusively on the mineral plagioclase within the Mount St Helens system.
