Geochemistry of Bedrock and Soils Near Yukon Anvil Mine

A thesis study analyzes multi-element geochemistry for bedrock, glacial overburden, and soils around the Anvil Mine lead-zinc deposits in Yukon. The research tests geochemical techniques for mineral exploration in areas with thick glacial cover, examining primary halos and secondary dispersion patterns of elements like Pb, Zn, Mo, Ba, Ni, Cr, Co, Cu, and Sn.

Use Cases

• Analyze trace element enrichment patterns (e.g., Ni, Cr, Co, Cu in amphibolite; Pb, Sn in rhyolite) to distinguish bedrock lithologies.
• Model secondary dispersion of Zn and Pb in glacial overburden and soils to delineate ore bodies like the Faro #2 deposit.
• Compare anomalous/threshold contrasts between cxZn and total Zn in overburden to assess hydromorphic indicator strength.
• Investigate the spatial extent of primary Pb, Zn, Mo, and Ba halos relative to the visible alteration envelope of the Faro ore zone.
• Evaluate background and threshold values for Cu, Pb, and Zn in till versus glaciofluvial deposits for exploration targeting.

Strengths

• Study focuses on three large, known stratabound lead-zinc deposits (Faro, Vangorda, Swim) providing real-world exploration context.
• Analysis covers multiple sample media: bedrock, glacial overburden, and soils, offering a multi-faceted geochemical view.
• Examines a specific suite of trace elements (Pb, Zn, Mo, Ba, Ni, Cr, Co, Cu, Sn) relevant to base metal exploration.

Limitations

• Data scope is confined to a single thesis study from a specific geographic area, limiting generalizability.
• Sample sizes and quantitative row/column counts for geochemical measurements are not provided in the available metadata.
• The nature and origin of some anomalies, such as the Pb anomaly in overburden, are noted as not fully understood.
