Little Kalzas Lake Geology: Stratigraphy and Structure of Yukon-Tanana Terrane

The Yukon-Tanana Terrane in the Little Kalzas Lake area consists of a lower quartzite package and an upper metavolcanic package. The layered metamorphic rocks are intruded by the multi-phase Little Kalzas orthogneiss complex and younger plutons. A pervasive transposition foliation and mineral lineation are developed throughout the area, with structures deformed by younger crenulation cleavages.

Use Cases

• Map regional stratigraphy based on described quartzite and metavolcanic packages.
• Analyze structural deformation based on descriptions of transposition foliation and folds.
• Study intrusive rock relationships based on the Little Kalzas orthogneiss complex and younger plutons.
• Model metamorphic rock assemblages based on described metavolcanic and marble units.

Strengths

• Detailed geological description of rock packages and structural features.
• Specific geographic focus on the Little Kalzas Lake area (105L/13) in central Yukon.
• Includes temporal references to intrusive phases (Jurassic?, Tertiary).

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 open_canada.
