Geochemistry of Devono-Mississippian Volcanic Rocks in Yukon's Finlayson Lake District

The Finlayson Lake district in southeastern Yukon contains geochemical data from metamorphosed volcanic, plutonic, and sedimentary rocks of a Late Paleozoic arc–back-arc system. These rocks host more than 40 Mt of polymetallic resources in volcanogenic massive sulphide (VMS) occurrences. The data, published by the Government of Yukon, supports interpretations of magmatic environments and their role in VMS mineralization localization.

Use Cases

• Modeling arc–back-arc magmatic processes based on geochemical signatures described in the dataset
• Identifying prospectivity criteria for volcanogenic massive sulphide (VMS) mineralization based on elevated HFSE and REE concentrations
• Comparing petrogenetic conditions between VMS-proximal and VMS-barren rock assemblages
• Supporting mineral exploration in similar geodynamic settings globally using the outlined criteria

Strengths

• Data is associated with a district hosting more than 40 Mt of polymetallic resources
• Geochemical analysis supports interpretations of specific arc and back-arc basin environments (Fire Lake, Kudz Ze Kayah, Wind Lake, Wolverine Lake)
• Published by the authoritative 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
• Data may reflect geographic bias inherent to the specific Yukon-Tanana terrane
