Mid-Cretaceous plutons intrude Upper Proterozoic to Mississippian metasedimentary rocks in the McQuesten River region, Central Yukon. The dataset describes three main plutonic rock groups and their spatial association with tin-silver and tungsten-gold mineralization. It is provided by the Government of Yukon and was last updated in April 2026.
Use Cases
- Map plutonic rock distribution based on described belts and intrusions.
- Analyze spatial associations between rock types and mineralization (tin-silver, tungsten-gold).
- Study fractional crystallization processes based on the concentrically zoned ZETA syenite intrusion.
- Compare plutonic suites with the Selwyn and Tombstone Plutonic Suites.
- Investigate contact aureoles and bimodal intrusive suites described in the region.
Strengths
- Detailed geological description of three main plutonic rock groups and their associations.
- Spatial context provided for mineralization types (tin-silver breccia veins, tungsten-gold skarns).
- Cogenetic link established through the fractional crystallization process of the ZETA intrusion.
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 region studied.
