Plateau South Gold Property Geochronology and Pb Isotope Data

Quantitative mineralogy, U-Pb geochronology, and Pb isotopic data provide insight into gold mineralization in central Yukon. The dataset includes precise ages for plutons (95.39 ± 0.03 Ma and 95.51 ± 0.03 Ma) and Pb isotope ratios from galena. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Modeling the timing of orogenic gold mineralization based on ca. 110-100 Ma metamorphism and mineralization ages.
• Identifying metal sources for mineralization based on Pb isotopic ratios from galena (206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb).
• Correlating intrusion-related mineralization with pluton emplacement based on ages of the Russell stock and Armstrong pluton.
• Investigating the relationship between regional metamorphism and hydrothermal fluid events based on 40Ar/39Ar geochronology of muscovite and sericite.

Strengths

• Includes precise geochronological dates with low uncertainty (e.g., 95.39 ± 0.03 Ma).
• Provides quantitative Pb isotopic data with specific ratios for two distinct groups.
• Focuses on a specific, documented mineral property (MINFILE 105N 034, 035, 036).

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 a single Yukon property.
