South-central Yukon bedrock geology in the Mendocina Creek and eastern Livingstone Creek areas comprises three distinct stratigraphic sequences. Metasedimentary and meta-igneous rocks are part of the Sheep Creek, Scurvy Creek, and Dycer Creek successions, correlated with Cassiar and Yukon-Tanana terranes. The data was published by the Government of Yukon and last updated on April 17, 2026.
Use Cases
- Map terrane boundaries based on stratigraphic sequences and fault descriptions.
- Analyze metamorphic facies and deformation phases based on greenschist- to amphibolite-facies descriptions.
- Correlate rock successions with regional assemblages like the Snowcap and Finlayson.
- Study intrusive relationships based on descriptions of augen meta-granite sills and dykes.
- Model geological structures based on descriptions of east- and west-verging thrust faults.
Strengths
- Describes three distinct stratigraphic sequences with specific rock types.
- Identifies correlations with established terranes (Cassiar, Yukon-Tanana).
- Details multiple phases of deformation and metamorphism.
- Provides a specific spatial offset for a terrane boundary (20 km east of the d'Abbadie fault).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified despite the 2026 update date.
