Kluane Ranges Bedrock Geology Map, White River Area

Wrangellian volcanic and sedimentary rocks in southwest Yukon underwent multiple deformation phases from Late Triassic to Miocene time. Bedrock mapping completed within the White River area documents these events, including Late Jurassic-Early Cretaceous compression and Cretaceous-Miocene strike-slip faulting. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.

Use Cases

• Modeling Late Paleozoic to Late Triassic volcanic and sedimentary rock sequences based on the description of Wrangellia.
• Analyzing structural deformation phases, including overturned folds and strike-slip faults, based on the described tectonic history.
• Studying graben formation and the relationship to Nikolai Formation flood basalts based on the described structural features.
• Investigating pre-Middle Triassic deformation events based on the mention of the Hasen Creek Formation.

Strengths

• The description provides a detailed geological history spanning Late Paleozoic to Miocene time.
• The dataset is provided by the authoritative Government of Yukon.
• The data was last updated on 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.
• The specific file formats are HTML and PDF, which may not be ideal for direct quantitative analysis.
