Lithogeochemical characterization of the Middle–Upper Devonian Road River Group and Canol and Imperial formations on Trail River, east Richardson Mountains, Yukon: age constraints and a depositional model for fine-grained strata in the Lower Paleozoic Richardson trough

A geological paper providing lithogeochemical characterization and a depositional model for fine-grained strata in the Lower Paleozoic Richardson trough. The study focuses on the Middle–Upper Devonian Road River Group and Canol and Imperial formations on Trail River in the east Richardson Mountains, Yukon. The dataset is hosted by the Government of Yukon and was last updated in March 2026.

Use Cases

• Analyze lithogeochemical characterization data to model depositional environments for the Road River Group.
• Use age constraints to correlate stratigraphic sequences of the Canol and Imperial formations.
• Apply the provided depositional model to interpret fine-grained strata within the Richardson trough.

Strengths

• Data is sourced from the authoritative Government of Yukon Geological Survey.
• The study provides a specific depositional model for a defined geological region and time period (Middle–Upper Devonian).
• Information was last updated in March 2026, indicating recent availability.

Limitations

• The core data is presented as a scientific paper, not a structured tabular dataset, limiting direct computational analysis.
• Sample data, row counts, and specific analytical columns are unavailable.
• Access requires contacting the Yukon Geological Survey, which may delay immediate use.
