Wernecke Breccia Development in Slats Creek Map Area

Wernecke breccia comprises numerous intrusive hematitic breccia zones exposed in the Wernecke and Ogilvie mountains of central Yukon. The dataset describes the development of these zones in the Slats Creek (106 D/16) map area, including their emplacement into Middle Proterozoic strata and associated mineralization of Cu, U, Co, Ag, and Au. It was published by the Government of Yukon and last updated in April 2026.

Use Cases

• Analyzing spatial correlation between breccia zones and intrusions based on the described magmatic linkage.
• Studying mineralization patterns of Cu, U, Co, Ag, and Au based on the described metasomatism.
• Modeling breccia genesis and invalidating previous models like evaporite diapirism based on the detailed geological description.
• Mapping regional deformation and metamorphism preceding brecciation based on the Racklan orogeny context.

Strengths

• Detailed geological description of breccia genesis, metasomatism, and mineralization.
• Specific geographic focus on the Slats Creek map area in the Wernecke Mountains.
• Includes discussion of invalidated previous models, providing a clear scientific stance.

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.
