Permian to Jurassic (ca. 268–252 Ma) geochronological data from the Yukon-Tanana terrane in the northern Canadian Cordillera. The dataset includes lithogeochemical data, U-Pb geochronology, and Hf isotope data of igneous and detrital zircons, compiled by the Government of Yukon. It supports a review of tectonic models for the closure of the Slide Mountain Ocean and the 'Klondike orogeny'.
Use Cases
- Reconstructing tectonic timelines based on U-Pb geochronology and Hf isotope data
- Analyzing regional metamorphism and deformation patterns based on lithogeochemical data
- Modeling supra-subduction zone arc development based on zircon dating evidence
- Correlating northern Cordilleran orogenies with events in the western USA based on reviewed evidence
Strengths
- Includes precise CA-TIMS U-Pb dating of zircon in plutons, with a cited age of ca. 260.9 Ma
- Combines lithogeochemical data with new U-Pb geochronology and Hf isotope data
- Provides a critical review of evidence for regional metamorphism spanning from Permian to Early Jurassic
Limitations
- Row count is unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Data may reflect geographic bias inherent to the Yukon region
