Late Neoproterozoic Limestone Stratigraphy Near Tillei and McPherson Lakes, Yukon

Late Neoproterozoic limestone exposures around Tillei and McPherson lakes in southeastern Yukon are documented. The limestone is lithologically similar to the Espee Formation but is in geological continuity with the Hyland Group. This dataset from the Government of Yukon, last updated in April 2026, may contain evidence for stratigraphic linkages between the Hyland and Ingenika groups.

Use Cases

• Correlating stratigraphic units based on lithological similarity to the Espee Formation mentioned in the description
• Investigating geological continuity between the Hyland and Ingenika groups based on the described structural relationship
• Modeling Cenozoic dextral displacement on the Tintina fault based on the described separation of age-equivalent sequences
• Analyzing paleobathymetry and platform/basin margins based on the interpretation of deposition in a high-standing region

Strengths

• Focuses on a specific geological region with extensive exposure of a thick limestone unit
• Provides a hypothesis for stratigraphic linkages between two major geological groups
• Last updated date is explicitly provided: 2026-04-17 15:53:08.178028

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Description metadata is limited; actual data quality requires manual inspection after download
