Stream Sediment and Water Geochemistry for Nahanni Map Area

GSC Open File D3772 provides geochemical data for stream sediments and waters in the Nahanni Map area (NTS 105I). The dataset includes analyses for over 35 elements in sediments and 15 constituents in water, originally released in 1982 and reanalyzed in 1999. It is published by the Geological Survey of Canada and hosted on the open_canada platform.

Use Cases

• Identify regional mineral deposit signatures based on trace element concentrations in stream sediments.
• Assess environmental baseline conditions based on water chemistry parameters like pH, alkalinity, and sulphate.
• Correlate sediment and water geochemistry for integrated watershed analysis.
• Map geochemical anomalies for exploration targeting based on listed elements like Au, Cu, Zn, and U.

Strengths

• Includes analyses for over 35 elements in stream sediments and 15 constituents in water.
• Data underwent re-analysis by INAA in 1999, suggesting quality control.
• Specific geographic focus on Nahanni Map area (NTS 105I).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data was archived and not updated since publication; freshness should be verified.
