Early Paleocene (62.3 ± 0.7 Ma to 59.1 ± 2.0 Ma) Ar-Ar geochronology and Pb isotopic analyses from the Rau gold-rich carbonate replacement deposit in central Yukon. The dataset likely contains geochemical and isotopic measurements from sulphides, intrusions, and host rocks. It was published by the Government of Yukon and last updated in April 2026.
Use Cases
- Modeling the genetic relationship between mineralization and intrusions based on Pb isotopic clustering with igneous feldspars.
- Determining the timing of mineralization events based on 40Ar/39Ar muscovite ages.
- Analyzing the geochemical distinction between intrusions based on comparisons with the McQuesten plutonic suite.
- Investigating the source of metals based on isotopic trends toward radiogenic compositions in host carbonate rocks.
Strengths
- Includes precise radiometric ages with reported uncertainties (e.g., 62.3 ± 0.7 Ma).
- Provides Pb isotopic analyses for sulphides, intrusions, and host rocks.
- Data is associated with a specific, well-described geological deposit (Rau deposit, central Yukon).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
