Teslin Area Stream Sediment Geochemistry, Yukon (1985-2014)

865 stream sediment and water samples collected in Yukon's Teslin area in 1985 were reanalyzed in 2014 for 53 elements. The Government of Yukon and Geological Survey of Canada conducted the original survey and subsequent upgrade. Results include raw digital data, PDF reports, and aqua-regia ICP-MS analysis details.

Use Cases

• Model regional mineral potential based on 53-element geochemical signatures.
• Compare historical (1985) and modern (2014) analytical results for the same samples.
• Map geochemical anomalies using the spatial coordinates of 865 sample sites.
• Analyze stream sediment composition for environmental baseline studies.

Strengths

• Includes 865 sample sites with both original (1985) and reanalysis (2014) data.
• 53 elements analyzed per sample using an ultra-trace aqua-regia ICP-MS package.
• Provides raw digital data, PDF method descriptions, and summary statistics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• 48 sites in protected areas were excluded from the 2014 reanalysis, creating a coverage gap.
• Row count is unknown, which may limit suitability assessment.
