Paleozoic Stratigraphy and Metallogeny of the Pelly Mountains, Yukon

Paleozoic rocks in the Pelly Mountains preserve greater than 150 million years of sedimentation, magmatism, and base-metal mineralization. A multi-year project initiated by the Government of Yukon focused on stratigraphy in the Quiet Lake (105F) and Finlayson Lake (105G) map areas. Field studies during summer 2015 examined Cambrian-Ordovician and Devonian-Mississippian rock successions.

Use Cases

• Analyze secular trends in regional tectonics based on stratigraphic intervals described.
• Study base-metal mineralization patterns based on descriptions of metalliferous volcanic rift basins.
• Compare rock assemblages between basins based on references to the Selwyn basin and Yukon-Tanana terrane.
• Model depositional environments based on descriptions of marine settings and extensional tectonism.

Strengths

• Focuses on a geological record spanning greater than 150 million years.
• Describes specific stratigraphic intervals: Cambrian-Ordovician and Devonian-Mississippian formations.
• Project outline includes preliminary field results from summer 2015.

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 map areas studied.
