Australian Geochronology Database With Radiometric Dating Results

Australia-wide geological sample data includes attributes for sample number, stratigraphic unit, rock type, location, and radiometric dating results. The database contains approximately 10 Megabytes of information compiled by the Bureau of Mineral Resources (BMR) in Australia. It covers hardrock areas across the country.

Use Cases

• Predict rock type from decimal latitude and longitude coordinates using geospatial models.
• Analyze correlations between stratigraphic unit and radiometric dating results from K-Ar, Ar-Ar, Rb-Sr, Sm-Nd tables.
• Map sample distribution by country, state, and region attributes for geological survey analysis.
• Link bibliographic references from the REFERENCES table to specific samples or dating results for provenance tracking.

Strengths

• Database size is specified as about 10 Megabytes.
• Contains multiple dating result tables (K-Ar, Ar-Ar, Rb-Sr, Sm-Nd, Pb-Pb zircon, SHRIMP).
• Includes geographic attributes like decimal latitude, longitude, country, state, and region.

Limitations

• Specific row counts and column counts for each table are unknown.
• Data is limited to Australia, with potential future additions for Antarctica and PNG.
• Temporal coverage and last update date are unspecified.
