Yukon-Tanana Terrane Stratigraphy and Mineral Occurrences South of Finlayson Lake

A stratigraphic framework report describes four revised map units of metasedimentary and metavolcanic rocks in the Yukon-Tanana Terrane south of Finlayson Lake. The report, published by the Government of Yukon, associates three of these geological units with specific mineral occurrences and deposits. It was last updated on April 17, 2026.

Use Cases

• Mapping regional geology based on described metasedimentary and metavolcanic units.
• Analyzing the spatial association between stratigraphic units and mineral deposits.
• Studying the provenance of coarse-grained metaconglomerates to refine geological interpretations.
• Identifying potential exploration targets based on unit-hosted deposits like Kudz Ze Kayah and Fyre Lake.

Strengths

• Report details four newly revised map units and subunits traced throughout the area.
• Associates three specific map units with named mineral occurrences and deposits.
• Last updated on April 17, 2026, indicating recent maintenance.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific Yukon-Tanana Terrane study area.
