Geological mapping data from the Mount Freegold district in Yukon's Dawson Range defines plutons and fault structures related to mineralization. The Government of Yukon produced this dataset, which was last updated on April 17, 2026. It focuses on a major extensional relay zone of the Big Creek fault system and mid to Late Cretaceous magmatic rocks.
Use Cases
- Analyze structural frameworks for mineralization based on descriptions of fault systems and relay zones
- Model magmatic-hydrothermal epochs based on references to distinct mineralization events over 35 million years
- Map pluton emplacement and relationships based on identified granite and Stoddart plutons
Strengths
- Specific temporal references, including the ca. 77 Ma Stoddart pluton and ca. 70 Ma Seymour Creek stock
- Defines a minimum 35 million-year interval for episodic fault movement and mineralization
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
