Late Triassic to Jurassic Plutons Atlas for Yukon Intermontane Terranes

Over 34 plutons are systematically described with new data including 47 U-Pb zircon dates, 44 Ar-Ar dates, and 187 whole-rock geochemical analyses. This atlas presents a geoscience dataset for plutons associated with porphyry copper deposits, compiled by the Government of Yukon and updated in April 2026. It aims to provide a regional framework for Late Triassic to Jurassic plutons and associated mineral occurrences in southern Yukon.

Use Cases

• Regional geological mapping based on pluton descriptions and maps
• Mineral deposit potential analysis based on association with porphyry Cu ± Au ± Mo deposits
• Geochronological studies based on U-Pb zircon and Ar-Ar dates
• Geochemical characterization based on whole-rock and isotope analyses
• Educational reference based on photomicrographs and photographs

Strengths

• Systematic description of over 34 plutons
• Includes 47 U-Pb zircon dates and 44 Ar-Ar dates
• 187 whole-rock geochemical analyses provide compositional data
• Complementary visual data includes photomicrographs, photographs, and maps

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 Yukon region
