Geochemical and U-Pb zircon age data from nine mid-Cretaceous plutons in the Coal River map area of southeastern Yukon. The dataset includes compositional analyses and precise ages determined via isotope dilution thermal ionization mass spectrometry (CA-TIMS). It was published by the Government of Yukon and last updated on April 17, 2026.
Use Cases
- Correlating pluton ages with regional tectonic events based on precise U-Pb zircon dates
- Analyzing magma source rock composition based on metaluminous to peraluminous geochemical characteristics
- Mapping the extent of the Tay River plutonic suite based on compositional similarity and age consistency
- Studying the cessation of deformation in the Cordilleran orogeny based on the unfoliated nature of the intrusions
Strengths
- U-Pb ages for nine plutons with high precision, ranging from 99.80 ± 0.03 to 97.70 ± 0.03 Ma
- Geochemical data includes rock composition (biotite ± hornblende quartz monzodiorite to granodiorite) and characteristics (metaluminous to peraluminous, reduced to oxidized)
- Interpreted ages are concordant within statistical uncertainty
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 Coal River map area
