Scheelite Dispersion Analysis in Yukon Drainage Sediments

A study analyzes scheelite, magnetite, and other mineral fractions in drainage sediments downstream of the Clea tungsten skarn deposit in Yukon. The research identifies three interdependent problems complicating tungsten survey interpretation: hydraulic sorting effects, rare-grain sampling errors, and source material covariance. It proposes a regression method to determine hydraulically equivalent mineral sizes for ratio-based analysis.

Use Cases

• Apply regression methods to determine hydraulically equivalent sizes of magnetite for finer scheelite grain sizes.
• Analyze scheelite/heavies or scheelite/mediums ratios to assess covariance in source materials from skarn deposits.
• Profile hydraulically equivalent scheelite concentrations to delineate locations of scheelite input to streams.
• Investigate mineral concentration differences between high and low energy stream environments characterized by sediment grain size.

Strengths

• Analysis covers multiple mineral fractions: scheelite, magnetite, heavies, mediums, and lights.
• Study documents up to one-hundredfold relative enrichment for scheelite in high-energy stream environments.
• Research proposes specific methodological remedies for sampling, subsampling, and analytical challenges.

Limitations

• Dataset size, row count, and specific column structure are unknown from the provided input.
• Sample data and raw measurements are unavailable, limiting immediate analytical utility.
• Findings are geographically specific to the Clea Property in Yukon Territory.
