140 km² of the Eocene Skukum volcanic complex, 60 km south-southwest of Whitehorse, unconformably overlies Cretaceous granitic and Precambrian metasedimentary rocks. The Government of Yukon provides this geological study, which describes an interlayered sedimentary-volcanic sequence and altered felsic pyroclastic flows up to 800 m thick. The formation provides a control on the paleotopography, depositional environment, and provenance of the Skukum area.
Use Cases
- Analyze paleotopography based on the interlayered sedimentary-volcanic formation.
- Study depositional environments based on described sedimentary units.
- Investigate volcanic complex structure based on fault-bounded, elliptical plan and intruded dykes.
- Model geological provenance based on the described formation.
Strengths
- Specific spatial extent of 140 km².
- Detailed geological description including thicknesses of approximately 500 m and 800 m for major units.
- Clear temporal context (Eocene, Cretaceous, Precambrian).
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.
