Carmacks Area Stream Sediment Geochemistry, Yukon (1985)

1985 survey data from 951 sample sites in the Carmacks area of Yukon, collected by the Geological Survey of Canada under the Canada-Yukon Mineral Development Agreement. The package includes reanalysis results from 2014 for 985 samples, analyzing 53 elements via ICP-MS. Original PDF reports and Excel data files are provided.

Use Cases

• Identify regional mineral deposit signatures based on 53-element geochemical profiles.
• Model stream sediment geochemical baselines for environmental studies based on aqua-regia digestion ICP-MS data.
• Compare original 1985 survey results with 2014 reanalysis data for temporal trend analysis.

Strengths

• 951 original sample sites provide broad spatial coverage for the Carmacks map area.
• 985 samples were reanalyzed in 2014 using an ultra-trace aqua-regia ICP-MS package for 53 elements.
• Includes original PDF documentation detailing survey methods and analytical data listings.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• 4 samples were not recovered for reanalysis due to a deficiency of available material.
