Major and Trace Element Analyses of Dalhousie Group Basaltic Rocks

Geochemical data provides major and trace element analyses for basaltic rocks from the Dalhousie Group. The dataset, published by author Jaroslav Dostal on figshare, is a single Excel table (XLSX) of 29.6 KB. It was last updated in April 2026.

Use Cases

• Analyze relationships between major element concentrations (e.g., SiO2, Al2O3, Fe2O3) to classify the volcanic rock series.
• Investigate tectonic setting using trace element ratios and spider diagrams derived from the provided elemental data.
• Correlate geochemical signatures from the Dalhousie Group basalts with other regional units to understand the Early Devonian tectonic evolution.

Strengths

• Data is openly available under a CC-BY-4.0 license.
• Dataset is structured in a single, standard XLSX file format for easy access.

Limitations

• The dataset is very small at 29.6 KB, indicating a limited number of rock samples or analyses.
• No row count or sample size is provided, making it difficult to assess statistical robustness.
• The description is sparse, lacking details on analytical methods, precision, or sample locations.
