Revised Bedrock Geology Map of Mount Nansen Area, Yukon

The Mount Nansen area in Yukon, Canada, is covered by this revised geological map. It compiles and re-interprets bedrock geology, defining a porphyry district centered on historic gold and silver production. The map integrates new mapping with previously undigitized data and geochronological samples from this study and the Yukon database.

Use Cases

• Identify potential mineral deposit locations based on the defined porphyry district and MINFILE occurrences.
• Analyze bedrock structure and geological history based on the compilation and reinterpretation of mapping.
• Correlate mineralization events with specific geological suites based on Late Cretaceous and Early Cretaceous porphyritic rock descriptions.
• Validate or update geochronological data based on integrated samples from the Yukon geochronology database.

Strengths

• Map integrates new fieldwork with previously undigitized 1:30,000 scale bedrock mapping.
• Geochronological data incorporates samples from this study and the Yukon geochronology database.
• Focuses on a defined 12 x 6 km district with historic gold-silver production.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Some geochronological samples from the database were omitted due to uncertain locations.
