The Southwest McQuesten-northern Carmacks area is primarily underlain by rocks of the Yukon-Tanana terrane, divided into two belts separated by the Willow Creek fault. The southern part is underlain mainly by rocks of Quesnellia and Stikinia, including Paleozoic metamorphic rocks, Upper Triassic volcanic rocks, and Early Jurassic granitoids. These geological units are described in a dataset published by the Government of Yukon, last updated on April 17, 2026.
Use Cases
- Map geological terranes and fault systems based on descriptions of the Yukon-Tanana terrane and Willow Creek fault.
- Identify prospective mineral districts based on comparisons to nearby areas like the Dawson Range mineral belt.
- Analyze rock types and ages based on descriptions of Permian metasedimentary rocks, Mississippian Reid Lakes complex, and Cretaceous Carmacks Group.
- Study post-accretion geological history based on descriptions of mid-Cretaceous plutons and Quaternary Selkirk volcanics.
Strengths
- Dataset provides detailed geological descriptions of multiple rock assemblages, terranes, and fault systems.
- Data is published by the Government of Yukon, an authoritative source for regional geology.
- Last update timestamp is explicitly provided: 2026-04-17 15:40:11.888380.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description states the area is 'under-explored', suggesting data completeness may be limited.
