A 2026 geological mapping project investigated the Kluane Schist, Ruby Range batholith, and Yukon-Tanana terrane in southwestern Yukon. Bedrock mapping at 1:50,000 scale followed a 400 m line-spaced aeromagnetic survey flown in 2010. The project was a joint initiative of the Yukon Geological Survey and Geological Survey of Canada under Natural Resources Canada's GEM program.
Use Cases
- Assessing porphyry Cu-Mo-Au potential based on the Ruby Range batholith upper level
- Evaluating epithermal Au-Ag mineralization potential in the Ruby Range batholith
- Identifying orogenic Au mineralization targets within the Kluane Schist
- Analyzing structural relationships between geological units like the Kluane Schist and Yukon-Tanana terrane
Strengths
- Mapping conducted at a detailed 1:50,000 scale
- Based on a 400 m line-spaced aeromagnetic survey flown in 2010
- Includes detrital zircon analyses providing deposition timing after ca. 94 Ma
- Identifies two significant metamorphic events dated at 82 and 70 Ma
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 survey area
