Three suites of intrusions, including 10–200 m thick mafic sills and 2–3 m wide alkaline dikes, are documented within Paleoproterozoic to Paleozoic sedimentary strata. The dataset describes northwest-verging folding and thrusting in the Wernecke Supergroup and gentle folds in younger groups. This geological update was published by the Government of Yukon on April 17, 2026.
Use Cases
- Map geological units based on described sedimentary groups and intrusive suites
- Analyze structural deformation patterns based on described folding, thrusting, and cleavage
- Model intrusion relationships based on thickness and composition of documented dikes and sills
- Study regional stratigraphy based on the sequence from Wernecke Supergroup to Bouvette Formation
Strengths
- Specific intrusion dimensions are provided, such as 10–200 m thick sills and 2–3 m wide dikes
- Structural features like northwest-verging folding and steeply dipping cleavage are explicitly described
- The temporal coverage spans from Paleoproterozoic to Paleozoic geological periods
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 the specific Yukon study area
