Late Cretaceous magmatic pulses from 80 to 65 million years ago are documented for the Klaza Au–Ag–Pb–Zn deposit in the Dawson Range, Yukon, Canada. The dataset likely contains U–Pb zircon dating results and zircon trace element data from a study by the Government of Yukon, published on open_canada. This research addresses the complex metallogeny of the gold belt by analyzing the Casino and Prospector Mt. magmatic suites.
Use Cases
- Modeling porphyry-epithermal deposit formation based on described Late Cretaceous magmatic pulses
- Analyzing zircon trace element signatures to infer melt source conditions
- Correlating magmatic suite ages (80-72 Ma, 72-65 Ma) with mineralization events
- Studying the transition from subduction to extension in porphyry belts using the described magmatic history
Strengths
- Focuses on a well-preserved type-example deposit (Klaza) for detailed study
- Provides age constraints for four magmatic pulses spanning Late Triassic to Late Cretaceous
- Includes zircon trace element data suggesting a common melt source
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, Canada region
