Six fission-track analyses from samples across a fault in the Takhini Hotsprings area, Yukon, indicate differential cooling histories. The Government of Yukon published this dataset, which was last updated on April 17, 2026. Results show east-side samples cooled through 100°C at 104.4 ± 11.9 Ma, while west-side samples cooled at 63.9 ± 8.5 Ma.
Use Cases
- Model differential uplift rates based on cooling age differences across the fault
- Analyze crustal weakness zones based on inferred fault boundary descriptions
- Compare thermochronometric results with previous studies across the Llewellyn Fault Zone
- Investigate the relationship between Jurassic/Triassic isopach changes and cooling history
Strengths
- Six fission-track analyses provide a quantitative basis for comparison
- Results include specific cooling ages with error margins (e.g., 63.9 ± 8.5 Ma)
- Dataset references a previous study for comparative validation
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 open_canada
