Volcano Mountain Nephelinite Petrology And Ultramafic Nodule Analysis

Petrological data from nephelinites and ultramafic nodules at Volcano Mountain, Yukon Territory. The dataset includes mineralogical compositions, geothermometry estimates between 930°C and 1350°C, and equilibrium pressure estimates from 20 to 45 kilobars for the nodules. It supports analysis of fractionation paths, melt separation depths, and comparisons to other North American occurrences.

Use Cases

• Analyze mineral abundances near glasses to model different fractionation paths.
• Use Pearce Element Ratios to identify non-comagmatic lava flows among the samples.
• Apply geothermometry on xenoliths to estimate temperatures between 930°C and 1350°C.
• Model polybaric pressure-temperature fractionation paths from silicate melt thermodynamics.
• Compare deformation textures and mineral compositions of dunite and lherzolite nodules to other western North American sites.

Strengths

• Provides specific temperature estimates (930°C to 1350°C) from geothermometry on xenoliths.
• Includes quantified pressure range estimates for nodules (20 to 45 kilobars).
• Contains detailed mineralogical data for olivine, Ti-rich diopside, ulvospinel, nepheline, leucite, calcite, and residual glass.

Limitations

• Sample size and row count are unknown, limiting statistical analysis.
• Data format is HTML, which is not structured for direct computational analysis.
• No columnar or tabular data structure is provided, requiring manual extraction for modeling.
