Yukon Targeted Geoscience Initiative: Bedrock Mapping in Glenlyon and Carmacks

Central Yukon bedrock mapping results from the Glenlyon and northeast Carmacks areas. The dataset likely contains geological information on metasedimentary, metavolcanic, and plutonic rocks of the Yukon-Tanana Terrane, including Carboniferous arc volcanic rocks and Early Jurassic and Cretaceous plutons. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Analyze tectonic terrane boundaries based on descriptions of the Yukon-Tanana, Cassiar, and Slide Mountain terranes
• Map fault systems and displacement based on the mention of dextral offset along the Needlerock and Big Salmon faults
• Study the distribution of plutonic suites based on the mention of Mississippian, Early Jurassic, and Cretaceous plutons
• Correlate rock successions based on descriptions of Carboniferous arc volcanic rocks and Devonian-Mississippian metaclastic rocks

Strengths

• Data is published by the Government of Yukon, an authoritative source for regional geology
• The description provides specific geological context including terrane names, rock types, and fault systems

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
