Geochronological and Lithogeochemical Data for Nahanni Region Intrusive Rocks

Intrusive rocks from the Nahanni region, southwestern Northwest Territories and southeastern Yukon, are analyzed. The dataset likely contains geochronological and lithogeochemical measurements, including U-Pb and Ar-Ar ages ranging from 97.5 to 95 Ma with cooling periods of 0.5 to 3 million years. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Modeling magmatic cooling histories based on reported U-Pb and Ar-Ar geochronology ages.
• Analyzing crustal derivation and arc-type settings based on rare earth element profiles and mineralogical descriptions.
• Correlating intrusive rock types with tungsten and polymetallic mineralization occurrences mentioned in the description.

Strengths

• Geochronological ages are explicitly reported as 97.5-95 Ma.
• Cooling periods are quantified as 0.5-1.5 m.y., with one intrusion noted at 3 m.y.
• The dataset is associated with a specific geological province and mineralization types.

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 Nahanni region study area.
