Government of Yukon provides geological data for the Grew Creek epithermal gold-silver prospect in south-central Yukon Territory. The dataset likely contains information on rock types, mineralization, alteration, and structural features based on the detailed geological description. It was last updated on April 17, 2026.
Use Cases
- Modeling epithermal gold-silver mineralization based on described geological setting and alteration types.
- Analyzing structural controls on mineralization based on the Grew Creek and Danger Creek faults.
- Studying hydrothermal alteration zones associated with rhyolitic dykes.
- Correlating mineralization timing with volcanic deposition based on K-Ar dates mentioned.
Strengths
- Includes specific K-Ar dates for volcanic rocks (51.4 ±1.8 Ma, 50.7 ±1.8 Ma) and hydrothermal alteration (51.5 ±1.8 Ma, 47.0 ±1.7 Ma).
- Provides detailed geological context including location, structural features, and rock sequences.
- Identifies specific minerals present (gold, electrum, pyrite, silver selenide).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
