1987 field season mapping at 1:50,000 scale southwest of Whitehorse, Yukon. The dataset describes Cretaceous and Triassic rock units, shear zones, volcanic complexes, and mineral occurrences. It was produced by the Government of Yukon.
Use Cases
- Analyze the distribution of epithermal gold-silver veins based on fault descriptions
- Study the relationship between pluton ages and volcanic stratigraphy based on U-Pb dating results
- Map the spatial extent of the Tally-Ho Shear Zone based on its 40 km length and trend
- Identify potential mineral exploration targets based on the three recognized types of mineral occurrences
Strengths
- Mapping conducted at a standardized 1:50,000 scale
- Includes specific U-Pb age dates for three plutons (220 ± 5 Ma, 58 ± 1 Ma, 119 ± 5 Ma)
- Describes a 40 km long shear zone with a specific trend
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
