Kluane Lake Stream Sediment Geochemistry, Southwest Yukon

1986 survey data and 2014 reanalysis results for 985 stream sediment samples from the Kluane Lake area in southwest Yukon. The work was undertaken by the Geological Survey of Canada with Yukon government partners under the Canada-Yukon Mineral Development Agreement. Samples were analyzed for 53 elements using an ultra-trace aqua-regia digestion ICP-MS package.

Use Cases

• Identify regional geochemical anomalies for mineral exploration based on 53-element analysis.
• Assess environmental baseline conditions in southwest Yukon based on stream sediment composition.
• Compare historical (1986) and modern (2014) analytical results for data quality studies.
• Map geochemical distributions for geological research based on 1005 original sample sites.

Strengths

• 985 samples successfully recovered and reanalyzed in 2014.
• 53-element analysis provides a broad geochemical profile.
• Includes both original 1986 survey data and 2014 reanalysis results.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• 28 samples were not recovered due to a deficiency of available material.
• 306 sample sites located in protected areas were excluded from the reanalysis.
