Preliminary Metallogenic Maps of Yukon with 11 Time Slices

Preliminary metallogenic maps for Yukon combine a digital geology map and a mineral occurrence database. The maps are presented as a series of eleven time slices from the Early and Middle Proterozoic to the Tertiary, showing geology and mineral occurrences classified by type and commodity. The Government of Yukon produced these maps, which were last updated on April 17, 2026.

Use Cases

• Analyze the distribution of mineral occurrences based on geological time slices
• Identify rock units with known mineral potential based on mapped commodity classifications
• Compare mineralization types (e.g., porphyry, skarn, vein) for specific geological periods
• Map the location of coal-bearing strata regardless of age
• Study the exploration frontier potential of Yukon based on recent discoveries like VMS and IRGS deposits

Strengths

• Maps are organized into eleven distinct geological time slices, providing temporal context
• Mineral occurrences are classified by both mineralization type and main commodity
• Includes specific examples of recent discoveries (VMS, IRGS, emeralds) illustrating frontier potential
• Separate maps for Mesozoic and Tertiary periods show occurrences subdivided by type

Limitations

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