Copper Deposit Geology and Host Rocks in Quill Creek, Yukon

Government of Yukon provides a geological thesis analyzing copper deposits in the Kluane Ranges. The study details stratigraphy from Permian to Triassic ages, cut by Cretaceous and Tertiary intrusions, and examines three prominent copper lode deposit types. It contrasts sulphur isotopic compositions in vein sulphides between the Station Creek Formation and Nikolai Greenstone.

Use Cases

• Classify copper deposit types (vein, disseminated, nickel-copper) based on host rock formations like Station Creek and Nikolai Greenstone.
• Analyze sulphur isotopic composition ranges to differentiate between closed-system metamorphic mobilization and open-system mineralization processes.
• Model the depositional environments (volcanic arc, back-arc basin, rift volcanism) for Permian and Triassic rock formations.
• Correlate specific lithologies (argillaceous and tuffaceous rocks, basalts) with their interpreted subaqueous or subaerial depositional settings.

Strengths

• Provides detailed stratigraphic analysis covering Permian to Triassic rock sequences.
• Identifies and contrasts three distinct types of copper lode deposits in the region.
• Includes specific geochemical analysis comparing sulphur isotopic compositions across two major formations.

Limitations

• Data is presented as a single thesis document in HTML format, not a structured, queryable dataset.
• Sample data and quantitative columnar information are unavailable for direct computational analysis.
• The temporal scope is fixed to the study's publication date, with no ongoing updates planned.
