Yukon Stream Sediment Geochemistry with Catchment Basin Analysis

Yukon Geological Survey re-analyzed stream sediment sample pulps from GSC's archives in Ottawa. The project funded by CanNor's Strategic Investments in Northern Economic Development program processed data from map sheets 105M, 105O, and part of 105P. This report and accompanying maps present results of catchment area delineation and weighted sums modeling to isolate geochemical signatures of known mineral deposits.

Use Cases

• Identify mineral deposit signatures based on modeled stream sediment geochemistry
• Analyze catchment basin characteristics for sample sites in Yukon
• Validate exploration targets using value-added geochemical data from map sheets 105M, 105O, and 105P
• Integrate processed geochemical data with regional geological maps

Strengths

• Data is derived from re-analysis of archived Geological Survey of Canada (GSC) sample pulps
• Analysis includes catchment area delineation for each sample and weighted sums modeling
• Project funded by Canadian Northern Economic Development Agency (CanNor)

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 specific Yukon map sheets analyzed
