Southern Yukon-Tanana Terrane between the Swift and Nisutlin rivers contains granite to ultramafic intrusions from four ages spanning Permian through Cretaceous. The dataset likely includes geochemical and geological data on these plutons, produced by the Government of Yukon. It was last updated on April 17, 2026.
Use Cases
- Analyze geochemical signatures of plutons based on Sr and Ti content mentioned in the description
- Model terrane amalgamation history based on intrusion ages spanning Permian through Cretaceous
- Identify potential for tin, tungsten, molybdenum, and beryl occurrences based on described hydrothermal systems
- Correlate Jurassic plutons with overlapping arcs like the Quesnel Terrane based on 'I-type' volcanic arc descriptions
Strengths
- Covers intrusions from four distinct geological ages (Permian, Jurassic, Cretaceous)
- Includes geochemical data such as Sr and Ti content for comparison between suites
- Focuses on a specific geographic region between the Swift and Nisutlin rivers
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to open_canada
