Geology and Mineral Occurrences of Gravel Creek and Irvine Lake Map Areas

Geological survey data describes the rock formations, structural features, and mineral occurrences within the Gravel Creek (105B/10) and Irvine Lake (105B/11) map areas in southeastern Yukon. The dataset details the Cassiar and Slide Mountain terranes, granitic intrusions, thrust faults, and mylonite zones. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Map geological terranes based on descriptions of Cassiar and Slide Mountain terranes
• Analyze structural features based on descriptions of thrust faults and mylonite zones
• Identify potential mineral exploration targets based on mentions of carbonate-hosted deposits and porphyry Mo prospects
• Study intrusive relationships based on descriptions of granitic batholiths and stocks

Strengths

• Detailed geological description of two map areas (105B/10, 11)
• Identifies specific rock types (e.g., basaltic metavolcanics, serpentinized ultramafic rocks, cherty metasediments)
• Describes structural features like the Zak thrust fault and a mylonite zone several tens of metres wide

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 map areas
