Lead isotopic compositions from galena and sulphide minerals constrain the origin and age of diverse mineralization styles in southern Wolf Lake, southeastern Teslin, and northern Jennings River map areas. Preliminary results indicate most mineralization is epigenetic and Mesozoic to Early Tertiary, while some occurrences suggest a syngenetic VMS origin of Devono-Mississippian age. This dataset was published by the Government of Yukon and last updated in April 2026.
Use Cases
- Determining the epigenetic vs. syngenetic origin of mineral deposits based on lead isotopic compositions.
- Estimating the approximate age of mineralization events using isotopic data.
- Correlating specific mineral occurrences (e.g., Dan, Logan, Logtung) with regional geological models.
- Investigating the nature of carbonate replacement deposits, skarns, greisens, and veins described in the area.
Strengths
- Data covers a wide variety of mineralization styles including carbonate replacement deposits, skarns, greisens, and veins.
- Lead isotopic compositions provide constraints on the nature and approximate age of individual occurrences.
- Preliminary results differentiate between epigenetic Mesozoic-Tertiary and syngenetic Devono-Mississippian origins.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
