Cenozoic Sedimentology and Structural Data for Denali Fault Basins

Yukon Territory's Amphitheatre Formation in the St. Elias Mountains is documented through sedimentology, palynology, and structural analysis. The multidisciplinary study covers two discrete basins, the northern Burwash basin and southern Bates Lake basin, along the Denali fault system. Data from the Government of Yukon spans the Eocene-Oligocene boundary and includes provenance studies and paleocurrent analyses.

Use Cases

• Modeling strike-slip basin evolution based on structural data indicating transpressional and transtensional settings.
• Analyzing sediment provenance based on light-mineral studies and clast-counts from Wrangellia and Yukon Crystalline Terranes.
• Correlating depositional environments with tectonic activity based on fault-controlled depocentre analysis.
• Studying diachronous sedimentation across the Eocene-Oligocene boundary using palynology and organic petrology data.

Strengths

• Study combines sedimentology, palynology, organic petrology, and structural analysis for a multidisciplinary view.
• Data covers two discrete basins, Burwash and Bates Lake, allowing comparative analysis.
• Analysis spans the Eocene-Oligocene boundary, providing a specific temporal context.

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 specific Yukon study area.
