Bedrock Geology Map of Morris Lake Yukon at 1:50,000 Scale

Geological map data for the Morris Lake area (105B/5) in southern Yukon at a 1:50,000 scale. The description details metamorphic rock belts of the Yukon-Tanana terrane, Cretaceous granitic batholiths, and inferred fault structures. The dataset was last updated on 2026-04-17 and is provided by the Government of Yukon.

Use Cases

• Analyze the distribution of metamorphic rock belts based on descriptions of oceanic and continental volcanic arc remnants.
• Study structural deformation based on inferred fault characteristics like the Ram Creek and Hidden Lake faults.
• Correlate rock units with regional geology based on mentions of the Klinkit Group correlation.
• Map the spatial relationship between Cretaceous granitic batholiths and older Paleozoic metamorphic rocks.

Strengths

• Provides detailed geological descriptions of rock types and structural features.
• Map data is at a standardized 1:50,000 scale.
• Includes inferred temporal ranges for geological events, such as Cretaceous and Permian-Jurassic activity.

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.
