Yukon Stream Sediment Geochemistry Data with Catchment Basin Analysis

Geochemical data from regional survey samples in Yukon underwent exploratory and principal component analysis, demonstrating geological control on commodity and pathfinder elements. Catchment basins were delineated for samples, and weighted sums models were generated for deposit types considered significant for exploration. The dataset includes maps showing stream water pH and hydromorphic dispersion elements, with anomalies identified for further investigation.

Use Cases

• Modeling mineral deposit potential based on weighted sums of commodity and pathfinder elements.
• Identifying exploration targets based on geochemical anomalies unrelated to known occurrences.
• Analyzing spatial associations between geochemistry and bedrock geology using principal components.
• Mapping catchment basin characteristics including stream water pH and hydromorphic dispersion.
• Leveling geochemical data using dominant geological units within delineated catchment basins.

Strengths

• Data interpretation is an improvement over raw geochemical data, as stated in the description.
• Models have been iteratively tested using known mineral occurrences in relevant map areas.
• Includes separate catchment maps for pH and hydromorphic dispersion elements.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• Levelling the geochemical data fails to fully account for bedrock enrichments due to mapping resolution limitations.
• Data may reflect geographic bias inherent to the Yukon region.
