Whitehorse Area Stream Sediment Geochemistry, 1985 Survey and 2014 Reanalysis

Regional stream sediment geochemical data from the Whitehorse area in southern Yukon (NTS 105D). The dataset includes results from 1003 original sample sites collected in 1985, with 964 samples reanalyzed in 2014 for 53 elements via aqua-regia ICP-MS. This work was conducted by the Geological Survey of Canada in conjunction with Yukon and federal departments.

Use Cases

• Identify regional geochemical anomalies for mineral exploration based on 53-element ICP-MS data.
• Compare baseline geochemistry between 1985 and 2014 reanalysis results.
• Map element distributions for environmental or geological studies using the geospatial sample locations.

Strengths

• Includes 964 samples reanalyzed in 2014 using a modern ultra-trace aqua-regia ICP-MS package.
• Provides data for 53 elements, offering a multi-element geochemical profile.
• Original survey covered 1003 sample sites, providing a broad spatial coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Samples from 79 sites in protected areas were excluded from reanalysis, potentially creating gaps.
