Aishihik Batholith U-Pb Zircon Dates for Mineral Potential Assessment

New U-Pb zircon dates from the Aishihik batholith in southern Yukon provide ages for granitoid rocks. The data, published by the Government of Yukon, indicates a range of ca. 190-180 Ma for the Long Lake plutonic suite and includes Early Mississippian protolith ages from orthogneiss samples. It was last updated on April 17, 2026.

Use Cases

• Assessing mineralization potential based on the described age range of 190-180 Ma.
• Comparing geological suites based on the Early Mississippian protolith ages mentioned.
• Targeting porphyry Cu-Au exploration based on the description of shallow-level intrusions.
• Validating previous TIMS dating results with the new, more precise SHRIMP and LA-ICPMS dates.

Strengths

• Dates are derived from precise SHRIMP and LA-ICPMS methods.
• Includes specific age ranges: ca. 190-180 Ma and Early Mississippian protolith ages.
• Data is sourced from the authoritative Government of Yukon.

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 batholith study.
