Government of Yukon data assesses the quality and confidence of digitized stream catchment areas for regional sediment samples. Rankings for sample location, catchment area, surface material, slope, and aspect are combined into reliability indices for mineral exploration targeting. The dataset includes assessments of data precision and bias from quality control samples and standard reference materials.
Use Cases
- Ranking catchment reliability for exploration targeting based on combined quality indices.
- Assessing downstream dilution effects based on catchment surface area proxy.
- Evaluating data precision for specific elements like Au, Cu, and As based on duplicate analyses.
- Identifying analytical bias shifts for key elements based on standard reference material assessments.
Strengths
- Includes quality indices combining rankings for location confidence, catchment area, surface material, slope, and aspect.
- Assesses data precision using field and blind duplicate analyses for selected elements.
- Evaluates analytical bias by comparing standard reference materials from two separate re-analysis campaigns.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
