A geological study of Devonian-era structures and stratigraphy near MacMillan Pass in eastern Yukon. The report describes three distinct structural blocks (North, Central, South) and their associated sedimentary exhalative zinc-lead-silver-barite deposits. It is accompanied by three 1:50,000-scale geological base maps covering NTS map sheets 105 O/1,2,7,8 and parts of 105 P/4,5.
Use Cases
- Analyze structural deformation patterns based on descriptions of thrust faults, folds, and high-angle reverse faults.
- Study stratigraphic sequences based on descriptions of Devonian chert, shale, limestone, and volcaniclastic rocks.
- Map mineral deposit locations based on references to the Tom and Jason zinc-lead-silver-barite deposits.
- Investigate depositional controls based on the hypothesis of Devonian fault control on strata patterns.
Strengths
- Includes three detailed 1:50,000-scale geological base maps.
- Provides a detailed structural and stratigraphic analysis of three distinct geological blocks.
- Focuses on a specific geological feature (the MacMillan Fold Belt) and associated mineral deposits.
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.
