Devonian-Mississippian Metavolcanic Stratigraphy and VHMS Potential in Southeastern Yukon

Southeastern Yukon's Finlayson Lake and Frances Lake map areas contain Upper Devonian and Lower Mississippian metavolcanic rocks organized into three thrust sheets. The dataset likely contains geological mapping and stratigraphic analysis of formations like the Waters Creek and Cleaver Lake formations, produced by the Government of Yukon. The data was last updated on April 17, 2026.

Use Cases

• Assessing volcanogenic massive sulphide (VHMS) deposit potential based on stratigraphic descriptions of metavolcanic rocks
• Structural geological analysis based on the interpretation of thrust sheets and Cretaceous normal faults
• Geological mapping and regional correlation based on formations like the Waters Creek, Tuchitua River, and Cleaver Lake formations

Strengths

• The description provides detailed stratigraphic and structural geological context for three thrust sheets
• The data is sourced from the Government of Yukon, an authoritative regional geological body
• The last update timestamp is April 17, 2026

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 studied
