Government of Yukon geological mapping describes sedimentary strata from the Paleoproterozoic Wernecke Supergroup to the Paleozoic Bouvette Formation. The report documents three major angular unconformities and gabbro intrusions likely equivalent to the ca. 1380 Ma Hart River Sills. Last updated on April 17, 2026.
Use Cases
- Map regional geological structures based on documented normal faults and gentle folds.
- Analyze stratigraphic relationships based on the three major angular unconformities described.
- Study igneous intrusions based on gabbro dikes and sills cutting Wernecke Supergroup rocks.
- Correlate volcaniclastic horizons based on the informal subdivision of the Bouvette Formation.
Strengths
- Report details specific geological units including Wernecke, Pinguicula, Hematite Creek, Windermere, and Bouvette formations.
- Provides temporal context with references to Paleoproterozoic, Mesoproterozoic, Neoproterozoic, and Paleozoic eras.
- Includes spatial context with reference to the Tiger deposit located ~20 km southwest.
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 a single map area in Yukon.
