Stratigraphy of the Mackenzie Mountains Supergroup in Yukon

Geological descriptions detail the stratigraphy of the Mackenzie Mountains supergroup in the Wernecke Mountains, Yukon. The report formalizes three new formations within the Hematite Creek Group and discusses regional thickness and lithofacies variations. The dataset is provided by the Government of Yukon and was last updated on April 17, 2026.

Use Cases

• Correlating regional stratigraphic units based on described formations like the Dolores Creek Formation.
• Analyzing paleobathymetric variation in ancient basins based on thickness and lithofacies data.
• Assessing the economic potential of sedimentary successions based on the described rock types.
• Studying the depositional environments of cyclic peritidal dolostone and shallow-marine siltstone.

Strengths

• Detailed lithological descriptions of multiple formations, including Dolores Creek, Black Canyon Creek, and Tarn Lake.
• Provides regional thickness and lithofacies variations for two formations.
• Formalizes stratigraphic nomenclature with three new formations assigned to the Hematite Creek Group.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The economic potential of the succession is explicitly stated as unknown.
