Lake Laberge Stream Sediment Geochemistry, Yukon (NTS 105E)

Geochemical data from 877 stream sediment and water sample sites collected in the Lake Laberge area in 1988. The Geological Survey of Canada, Department of Indian Affairs and Northern Development, and Government of Yukon conducted the survey. In 2014, 962 samples were reanalyzed for 53 elements using ultra-trace aqua-regia digestion ICP-MS.

Use Cases

• Identify mineral deposit signatures based on 53-element geochemistry
• Map regional geochemical anomalies for exploration targeting
• Compare original 1988 and 2014 reanalysis results for temporal consistency
• Analyze stream sediment composition for environmental baseline studies

Strengths

• 877 original sample sites provide spatial coverage
• 962 samples reanalyzed in 2014 with modern ultra-trace ICP-MS methods
• 53-element analytical package offers multi-element characterization

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
