The Finlayson Lake district in Yukon contains over 30 Mt of volcanogenic massive sulphide mineralization. Preliminary fieldwork from 2017 logged seven drill holes intersecting stratigraphic hanging walls and footwalls of the Fyre Lake, Kudz Ze Kayah, and GP4F deposits. The stratigraphic results reveal laminated volcaniclastic rocks interbedded with clastic or intrusive rocks, reflecting changes in depositional environments from Late Devonian to Early Mississippian.
Use Cases
- Re-evaluating chronostratigraphic frameworks based on logged drill hole stratigraphy
- Analyzing changes in depositional environments based on interbedded volcaniclastic and clastic rocks
- Studying tectonomagmatic regimes based on stratigraphic results from Late Devonian to Early Mississippian
- Groundwork for future petrologic, isotopic, and geochronologic studies of VMS deposits
Strengths
- Focuses on a district containing over 30 Mt of volcanogenic massive sulphide mineralization
- Includes stratigraphic results from seven drill holes logged during fieldwork in 2017
- Provides groundwork for future studies on petrology, isotopes, and geochronology
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
