Landsat TM Thermal Imagery for Structural Interpretation of the Tintina Trench

West-central Yukon's Tintina Trench is analyzed using digitally enhanced Landsat Thematic Mapper thermal imagery. The study divides visible linear features into first, second, and third order lineaments to interpret the structure of the Tintina Fault Zone. This dataset was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Mapping fault strands based on NW-SE trending first and second order lineaments.
• Identifying recent fault activity based on evidence of sag ponds and fresh fault scarps.
• Analyzing post-strike-slip deformation based on NE-SW trending lineaments cutting across the trench.
• Interpreting regional structural grain based on preferred orientations of third order lineaments.

Strengths

• Data is derived from Landsat Thematic Mapper thermal imagery, a standardized satellite source.
• Structural interpretations are based on a systematic classification of lineaments into three orders.
• The dataset is provided by the Government of Yukon, an authoritative regional source.

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 the specific study area in west-central Yukon.
