YukonAge 2002: Isotopic Age Determinations for Yukon Rock Units

Over 1500 age determinations derived from over 1100 rock samples from Yukon Territory. The data is compiled from published and unpublished reports, including theses, and is provided in a relational database format. The Government of Yukon maintains this dataset, which was last updated in April 2026.

Use Cases

• Querying rock ages based on absolute age (in Ma) for regional geological modeling.
• Locating samples geographically using NTS map sheet, latitude/longitude, or UTM constraints.
• Identifying source materials by author or journal title for bibliographic research.

Strengths

• Over 1500 age determinations provide a substantial sample base.
• Data sourced from over 1100 rock samples enhances representativeness.
• Includes unpublished and authorized age determinations, expanding beyond public literature.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The primary database requires Microsoft Access 2000, a legacy software, for full querying.
