Yukon Stream Sediment Geochemistry from 1976-1977 Surveys

Regional stream sediment geochemical data from the Nash Creek and Larson Creek survey areas in Yukon, Canada. The data includes results from original surveys conducted in 1976 and 1977, plus reanalysis results from 1990 and a later Yukon Database Upgrade Project. Information is provided in PDF reports and Excel files containing raw field and analytical data.

Use Cases

• Identify regional geochemical anomalies for mineral exploration based on sediment element concentrations
• Compare historical survey results with modern reanalysis data for methodological studies
• Map the distribution of specific elements like gold across the survey areas

Strengths

• Includes original 1976-1977 survey data plus reanalysis results from 1990 and a later upgrade project
• Analytical data covers 53 elements from an ultra-trace aqua-regia digestion ICP-MS package
• Provides PDF documentation with survey descriptions, methods, and summary statistics

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic and temporal bias inherent to the original survey periods
