Placer Gold Composition and Morphology in South Nahanni River Drainage

Government of Yukon published a dataset on placer gold grains from the South Nahanni River drainage in Northwest Territories. The dataset likely contains morphological shape analysis and compositional data for Au-Ag-Cu-Hg values from electron microprobe analysis, comparing grains from Selena Creek and isolated showings. The dataset was last updated on April 17, 2026.

Use Cases

• Trace gold source provenance based on compositional analysis of Au-Ag-Cu-Hg values
• Compare morphological characteristics of gold grains from different locations
• Analyze the relationship between copper content and gold grain origin
• Validate geological models using published compositional data comparisons

Strengths

• Gold grains are typically >700 fineness, indicating high purity
• Mercury content is below detection levels (<0.20%)
• Dataset includes comparison with published morphological and compositional data from other regions

Limitations

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