Yukon Surficial Geology Line Features and Age Attributes

Over 195 compiled surficial geology maps provide approximately 80% coverage of the Yukon territory. The GIS dataset includes line features such as geological contacts, glacial limits, and landforms, with polygon attributes capturing surficial material, texture, and age. Maps range in scale from 1:250,000 to 1:10,000 and were produced by agencies including the Yukon Geological Survey and Geological Survey of Canada.

Use Cases

• Model permafrost distribution and thermokarst depressions using point features and age attributes.
• Analyze glacial landform patterns, including eskers and moraines from line features, for paleo-environmental reconstruction.
• Assess geotechnical risks by mapping landslide and fault locations from line and point feature data.
• Support mineral exploration by correlating surficial material and texture attributes with geological contacts.

Strengths

• Compilation of over 195 individual maps ensures broad spatial coverage.
• Standardized attributes include surficial material, texture, age, and geomorphological processes.
• Maps provide multi-scale detail, ranging from 1:250,000 to 1:10,000.

Limitations

• Spatial coverage is approximately 80%, leaving gaps in the territory.
• Original maps were produced by diverse agencies, potentially introducing inconsistency in source data quality.
• Dataset size and specific feature counts (rows) are not provided.
