Ancient Pacific Margin Stratigraphic Sections for Yukon-Tanana Terrane

The Ancient Pacific Margin NATMAP project provides updated composite stratigraphic sections for the Finlayson Lake district, Glenlyon, Wolf Lake, Jennings River, Aishihik Lake, and northern Dawson Range areas. This data from the Government of Yukon shows the Yukon-Tanana Terrane originated as a mid- to late Paleozoic arc system. Its evolution includes arc-building, rifting, back-arc basin development, and deformation from Late Devonian to early Pennsylvanian.

Use Cases

• Modeling Paleozoic arc system evolution based on stratigraphic framework data
• Identifying potential volcanogenic massive sulphide deposits based on described arc rifting and back-arc basin events
• Comparing regional geology across the Finlayson Lake, Glenlyon, Wolf Lake, Jennings River, Aishihik Lake, and Dawson Range areas
• Analyzing the timing of arc-building events, deformation, and metamorphism from Late Devonian to Permian

Strengths

• Data covers multiple specific geographic areas: Finlayson Lake district, Glenlyon, Wolf Lake, Jennings River, Aishihik Lake, and northern Dawson Range
• Project is in its second year, indicating ongoing updates and refinement
• Provides a detailed temporal framework from Late Devonian to mid-Permian

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 open_canada, focusing on northern British Columbia and Yukon
