Yukon Stream Sediment Geochemistry 1976-2006

1976-2006 data compilation contains over 30,000 stream sediment samples from Yukon, Canada. The release includes results from multiple analytical methods (AAS, INAA, ICPMS) with improved detection limits and location accuracy for geochemical exploration.

Use Cases

• Compare element concentrations from ICPMS, INAA, and AAS analyses to assess method-specific detection limits for mineral exploration.
• Analyze spatial patterns in pathfinder elements like Au, As, Sb, and W from INAA data to identify regional mineralization trends.
• Use the RGS_All feature class to build a unified model predicting elemental anomalies from multi-method geochemical data.
• Investigate sample location accuracy improvements across the RGS_HEON and updated datasets for precise spatial analysis.

Strengths

• Over 30,000 physical samples provide substantial spatial coverage for the Yukon region.
• Includes reanalysis of more than 24,000 samples using ICPMS for upgraded detection limits and a broader element range.
• Data organized into six distinct feature classes (e.g., RGS_ICPMS, RGS_All) by analytical method for comparative study.

Limitations

• AAS method data is noted as partially superseded and cannot provide accurate determinations for REE, Ta, Nb, As, Sb, Sn, Hg, Cr, or Au.
• Sample collection ended in 2006, making the data temporally stale for contemporary environmental baseline studies.
• Specific row counts, column schemas, and sample data for each feature class are not provided in the input.
