GSC Open File 1649 contains analytical data from 917 sites in the Frances Lake area of southeastern Yukon. Stream silt sediments were analyzed for 38 elements plus loss-on-ignition, and corresponding waters were analyzed for uranium, fluoride, and pH. The Government of Yukon published this data, which includes ICP-MS re-analysis of archived samples.
Use Cases
- Identify potential mineral deposits based on trace element concentrations in stream sediments.
- Assess baseline environmental water quality based on uranium, fluoride, and pH measurements.
- Correlate sediment geochemistry with water chemistry from the same 917 sample sites.
- Re-analyze historical sediment samples using modern ICP-MS techniques.
Strengths
- Data covers 917 specific sample sites, providing a substantial spatial sample.
- Sediment analysis includes 38 elements plus loss-on-ignition, offering a multi-element geochemical profile.
- Includes paired water analysis for uranium, fluoride, and pH at corresponding sites.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the Frances Lake area survey.
