Yukon Stream Sediment and Water Geochemical Survey

623 stream sites in southwestern Yukon provide geochemical data for 36 elements in sediments, plus water measurements for uranium, fluoride, and pH. This dataset was compiled by the Government of Yukon and published as GSC Open File 2859/EGSD Open File 2001-11(D). The data was last updated on the platform in April 2026.

Use Cases

• Identify anomalous concentrations of gold (Au), copper (Cu), or lead (Pb) in stream sediments to guide mineral exploration targeting.
• Analyze correlations between sediment element concentrations like arsenic (As) or mercury (Hg) and water pH values to model element mobility.
• Map regional geochemical baselines for elements like iron (Fe) and manganese (Mn) using the 623 sample site locations.
• Assess environmental background levels by comparing loss-on-ignition data in sediments with trace element concentrations.

Strengths

• Data covers 36 specific elements (Ag, As, Au, etc.) plus water parameters for a focused analysis.
• Includes measurements from 623 distinct stream sampling sites, providing regional coverage.

Limitations

• Sample size of 623 sites may be sparse for high-resolution spatial modeling across the entire survey area.
• Data originates from a report published in 2001, so temporal recency for dynamic processes is limited.
• Unknown column structure and lack of sample data preview may complicate initial data loading and interpretation.
