Yukon Stratigraphy Summary for Southeast NTS Sheets 95D/8 and 95C/5

Sedimentary strata within NTS map sheets 95C/5 and 95D/8 in southeast Yukon have a combined thickness ranging between 5000 and 15000 m. Depositional ages range from Proterozoic to Paleocene, grouped into eight successions reflecting the tectonic framework of the Canadian Cordillera. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.

Use Cases

• Model regional tectonic history based on succession boundaries and unconformities.
• Analyze sedimentary depositional environments based on lithological facies zonation.
• Study stratigraphic thickness and age ranges for geological mapping.
• Investigate depositional hiatuses and unconformities within successions.

Strengths

• Provides a thickness range of 5000 to 15000 meters for the combined strata.
• Covers depositional ages from Proterozoic to Paleocene.
• Organizes data into eight distinct stratigraphic successions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Proterozoic, Late Paleozoic, Mesozoic and Cenozoic successions are only locally exposed.
