Bedrock mapping of parts of the Whitehorse and Teslin map areas in Yukon was conducted in the summer of 2012. The work characterizes the Cache Creek terrane, identifies new formations and intrusive complexes, and defines structural relationships with Stikinia and the Whitehorse trough. The dataset is provided by the Government of Yukon and was last updated on 2026-04-17.
Use Cases
- Analyze terrane boundaries and structural relationships based on descriptions of the Cache Creek terrane, Stikinia, and Whitehorse trough.
- Model phases of compressional deformation based on identified west-verging and east-verging thrust faults.
- Identify potential mineralization styles based on associations with ultramafic bodies or Cretaceous intrusions.
- Characterize newly identified geological units based on the Michie formation and gabbroic intrusive complexes.
Strengths
- Mapping improves upon previous 1:250,000 scale knowledge, suggesting higher resolution.
- Identifies two main phases of compressional deformation and three main styles of mineralization.

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 map areas.
