Amphibole Database for Electron Microprobe Analysis

A spreadsheet tool for calculating reliable mineral formulae from electron microprobe analyses of amphiboles. It was authored by Michael Henderson and last updated on May 28, 2026. The dataset is a 2.8 MB XLS file available under a CC-BY-4.0 license.

Use Cases

• Calculate amphibole mineral formulae based on electron microprobe data mentioned in the description.
• Estimate the amount of oxygen replacing hydroxyl in the W site of amphiboles as described.
• Validate or standardize amphibole formula calculations using the provided spreadsheet method.

Strengths

• Provides a specific calculation method for amphibole formulae, as described.
• The dataset is openly licensed under CC-BY-4.0.
• The file size is 2.8 MB, indicating a focused, non-bulky resource.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
