Granite Lake Bedrock Mapping and Geological Relationships, Southwest Yukon

Bedrock mapping conducted during the summer of 2013 in the Granite Lake area of southwest Yukon. The work identified tectonostratigraphic elements including the Yukon-Tanana terrane, Kluane schist, and Bear Creek assemblage, and intrusive phases from the Cretaceous and Paleocene. The data was produced by the Government of Yukon as part of a multi-year geological investigation.

Use Cases

• Modeling structural geology based on described northeast dipping structural stack.
• Identifying potential for gold mineralization based on similarities to the Juneau gold-belt.
• Analyzing tectonic relationships between identified terranes and assemblages.
• Mapping intrusive phases and their contacts with host rocks.

Strengths

• Mapping was conducted as part of a structured multi-year project.
• Identifies specific tectonostratigraphic elements and intrusive suites.
• Provides comparative analysis with geological systems in southeast Alaska.

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 survey area.
