Bedrock Geology of Teslin Mountain and East Lake Laberge, Yukon

The Government of Yukon published this dataset on April 17, 2026. It describes bedrock geology, including the Middle Triassic Joe Mountain Formation and Upper Triassic Lewes River Group volcanic sequences. The data covers the Teslin Mountain and east Lake Laberge areas in south-central Yukon.

Use Cases

• Map volcanic arc distribution based on descriptions of the Joe Mountain Formation and Lewes River Group.
• Analyze stratigraphic variations based on descriptions of carbonate subbasins from Carnian to Rhaetian.
• Model structural deformation based on descriptions of east-west trends and north-northwest trending folds and faults.
• Study post-accretion igneous activity based on mentions of Late Cretaceous Open Creek volcanic complex.

Strengths

• Data is sourced from the authoritative Government of Yukon.
• The description provides specific geological formations and structural features.
• The dataset 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.
• Data may reflect geographic bias inherent to open_canada, focusing on a specific Yukon region.
