Yukon Stream Sediment Geochemistry 1976-2006

1976 to 2006 regional stream sediment geochemical data compilation for Yukon, comprising over 30,000 samples. The dataset updates a 2003 compilation and includes results from reanalysis of more than 24,000 samples via ICPMS, AAS, and INAA methods, organized into six feature classes.

Use Cases

• Analyze elemental concentrations from ICPMS data to identify regional geochemical anomalies for mineral exploration
• Compare detection limits and element ranges across AAS, INAA, and ICPMS analytical methods for method validation studies
• Map sample locations with improved accuracy for spatial analysis of sediment geochemistry
• Integrate data from the RGS_All feature class containing all AAS, INAA, and ICPMS results for comprehensive trend analysis

Strengths

• Over 30,000 geochemical samples provide substantial spatial coverage
• Includes reanalysis of more than 24,000 samples with upgraded ICPMS detection limits
• Data spans a 30-year collection period from 1976 to 2006
• Organized into six distinct feature classes by analytical method for structured access

Limitations

• AAS method data is noted as partially superseded and cannot provide accurate determinations for specific elements like REE, Ta, Nb, As, Sb, Sn, Hg, Cr, or Au
• Sample collection ended in 2006, limiting temporal recency for contemporary studies
• Specific row counts, column counts, and file sizes are unknown from the input
