The Upper Jurassic to Lower Cretaceous Tantalus Formation in Yukon contains gravel-bed river deposits and localized coal reserves. Government of Yukon data includes geological interpretations of depositional environments and provenance analysis using detrital zircon age profiles. The dataset was last updated on April 17, 2026.
Use Cases
- Modeling braided and meandering gravel-bed river depositional environments based on described facies.
- Assessing potential for undiscovered coal reserves based on descriptions of floodplain abandonment.
- Analyzing sediment provenance and terrane contributions based on detrital zircon data.
- Evaluating the likelihood of conventional oil or gas reserves based on described lack of trapping mechanisms.
Strengths
- Data originates from the Government of Yukon, an authoritative geological source.
- The description provides detailed geological context for the formation's origin and composition.
- Files are available in multiple formats including XLS, XLSX, HTML, and PDF.
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.
