Granitic Rocks and Mineral Deposits of the Whitehorse Yukon Map-Area

Government of Yukon's report distinguishes four granitic rock types in the Whitehorse Map-Area. The stratigraphic, compositional, and textural data are sufficient to differentiate Mid-Jurassic quartz monzonite, Mid-Cretaceous quartz monzonite, Upper Triassic-Lower Jurassic granodiorite, and Lower Tertiary quartz granites. The report associates specific intrusives with mineralization and assesses potential for intrusion-related mineral occurrences.

Use Cases

• Distinguish granitic rock types based on stratigraphic, compositional, and textural data mentioned in the description
• Associate mineralization potential with specific intrusive rock types based on the described associations
• Evaluate prospectivity for porphyry copper mineralization based on the alteration and polymetallic nature described for Lower Tertiary subvolcanic rocks
• Compare Upper Triassic granodiorite batholiths with similar-age rocks in British Columbia based on the described distinguishing nature

Strengths

• Report distinguishes four specific granitic rock types: Mid-Jurassic pink quartz monzonite, Mid-Cretaceous biotite quartz monzonite, Upper Triassic-Lower Jurassic hornblende granodiorite, and Lower Tertiary smoky quartz granites
• Identifies associations between two intrusive types and significant mineralization
• Provides comparative analysis distinguishing Upper Triassic granodiorite from porphyry copper-bearing rocks in British Columbia

Limitations

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