Bedrock Geology Map Notes for the Fire Lake Area, Yukon

Geological mapping notes describe stratigraphic units and intrusive rocks around the Fyre Lake Cu-Co-Au deposit in southeastern Yukon. The report establishes continuity with the nearby Grass Lakes map area and reinterprets structural boundaries. The Government of Yukon published this information on April 17, 2026.

Use Cases

• Correlating stratigraphic units between map areas based on descriptions of chlorite schist and quartz-rich metaclastic units.
• Re-evaluating regional geological structures based on the reinterpretation of shear zones and klippe boundaries.
• Identifying potential mineral exploration targets based on the described spatial association of deposits with mafic and ultramafic intrusive rocks.
• Studying the composition and relationships of intrusive rocks like the Simpson Range Plutonic Suite based on described wall rocks and pendants.

Strengths

• The description provides specific geological unit names and rock types, such as chlorite schist, phyllite, and quartz porphyry.
• It includes a reinterpretation of structural features, contrasting new observations with previous mapping.
• The dataset is associated with a specific government organization, the Government of Yukon.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data format is HTML/PDF, which may require parsing to extract structured information.
