The Paleoproterozoic Slab volcanics occur in three localities in the Wernecke Mountains, Yukon. The largest exposure is a 0.6 x 0.25 km block of mafic to intermediate lava flows at Slab Mountain. This dataset is provided by the Government of Yukon and was last updated on 2026-04-17.
Use Cases
- Correlating volcanic units with plutonic intrusions based on geochemical similarity mentioned in the description
- Analyzing hydrothermal alteration associated with breccia emplacement based on mineralogical descriptions
- Mapping Paleoproterozoic volcanic exposures based on the three described localities
- Studying crustal block foundering processes based on the relationship with the Wernecke Breccia zone
Strengths
- Description includes specific spatial dimensions (0.6 x 0.25 km block)
- Description provides specific geological ages (1.60 Ga, 1.71 Ga)
- Description details mineralogical composition (plagioclase, scapolite, biotite, magnetite)
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 specific localities in the Wernecke Mountains
