A stratigraphic record extending approximately 130,000 years documents glacial and sedimentary deposits in Granite Creek, Yukon. Detailed study of placer mining operations identified multiple gold-bearing sedimentary units from at least two glacial episodes. This dataset from the Government of Yukon highlights processes important to gold concentration in alpine glaciated environments.
Use Cases
- Modeling placer gold concentration processes based on glacial and interglacial sedimentary units.
- Correlating alpine till units to MIS 4 glacial stages based on the stratigraphic record.
- Identifying high-energy depositional environments based on descriptions of advance and retreat outwash sequences.
- Studying proglacial lake formation based on evidence of ice-damming by the Cordilleran Ice Sheet.
Strengths
- Stratigraphic record extends approximately 130,000 years.
- Identifies multiple gold-bearing sedimentary units representing glacial, interglacial, and modern processes.
- Correlates alpine till units to MIS 4, which has not been identified elsewhere in central Yukon.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
