A geological map depicts bedrock formations at the western edge of the ancient North American continent in southern Yukon. The map, produced by the Government of Yukon, illustrates three major elements: tilted strata of the Cassiar Terrane, overthrust rocks of the Yukon-Tanana Terrane, and post-orogeny granitic bodies. It was last updated on April 17, 2026.
Use Cases
- Analyzing tectonic accretion patterns based on the depiction of Mesozoic terranes.
- Studying structural geology based on the representation of west-dipping structural stacks and thrust faults.
- Mapping granitic intrusions based on the post-orogeny granitic bodies described.
- Comparing geological units based on the differentiation between Cassiar and Yukon-Tanana terranes.
Strengths
- Map is produced by the Government of Yukon, an authoritative source.
- The description provides a detailed geological context of the mapped area.
- The map is available in HTML and PDF formats.
- 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.
