Late Jurassic Gilbert-Type Delta Anatomy in Yukon's Tantalus Formation

A geological analysis of a Late Jurassic Gilbert-type delta within the Tantalus Formation in the Yukon's Whitehorse Trough. The dataset likely contains architectural descriptions of foreset units, sediment types, and deformation features from exposures at the Whitehorse Coal deposit, 26 km south-southwest of Whitehorse. It was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Modeling delta progradation dynamics based on descriptions of foreset units and downlap patterns.
• Analyzing sediment transport mechanisms based on descriptions of inertia-dominated foresets and graded sandstone beds.
• Studying lacustrine depositional environments based on evidence of a lake at least 6 meters deep.
• Investigating deformation processes based on descriptions of foreset progradation over under-compacted clays.

Strengths

• Analysis is based on exposures at a specific location (Whitehorse Coal deposit, 26 km SSW of Whitehorse).
• Description includes specific geological features like foresets over 5 meters and a lake depth of at least 6 meters.
• Published by a governmental organization (Government of Yukon).

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 the single study location.
