Bedrock Geology of the Truitt Creek Map Area, Yukon-Tanana and Cassiar Terranes

Geological mapping describes the Tummel fault zone separating Paleozoic strata of Cassiar Terrane from Yukon-Tanana Terrane rocks in south-central Yukon. The dataset includes descriptions of rock types, intrusions like the Glenlyon Batholith, and interpretations of fault displacement. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Map tectonic terrane boundaries based on descriptions of the Tummel fault zone
• Analyze contact metamorphism effects based on interpretations related to the Glenlyon Batholith
• Study rock unit correlations based on mentions of Kechika and Askin Groups
• Investigate plutonic intrusions based on data on the Telegraph Plutonic Suite
• Assess post-mid-Cretaceous fault displacement based on the interpretation requiring minimal movement

Strengths

• Focuses on a specific map area (NTS 105L/1) in south-central Yukon
• Describes multiple rock types including granodiorite, diorite, greenstone, serpentinite, and chert
• Includes interpreted time ranges for plutonic suites (348-350 Ma) and fault displacement

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 open_canada
