Tectonic Assemblage Map of Yukon-Tanana Terrane at 1:1 Million Scale

A 1:1,000,000 scale map delineates the Yukon-Tanana Terrane, a pericratonic geological unit in Yukon and northern British Columbia. The Government of Yukon produced this map, which was last updated on April 17, 2026. The terrane consists of Paleozoic metamorphosed rocks and hosts significant base metal deposits like Wolverine and Kudz Ze Kayah.

Use Cases

• Analyze tectonic boundaries and terrane relationships based on the mapped assemblage.
• Identify potential mineral exploration targets based on described base metal occurrences.
• Study paleogeographic evolution of pericratonic terranes relative to the Laurentian craton.
• Correlate isotopic and provenance data from Paleozoic metamorphic rocks with Archean and Proterozoic sources.

Strengths

• Map is produced at a standardized 1:1,000,000 scale for regional analysis.
• Description explicitly names specific mineral deposits (Wolverine, Kudz Ze Kayah) within the terrane.
• Data is provided 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.
• The description is technical but lacks specifics on data format and structure.
