Government of Yukon data describes post-depositional hydrothermal alteration in White Channel sediments and bedrock, divided into three zones: Bleached, Iron, and Footwall. The zones are characterized by secondary clay minerals and anomalously high trace element concentrations of Fe, Mn, As, Sb, Hg, Co, Ba, and S. The dataset suggests a hydrothermal style of gold mineralization may exist in addition to initial placer gold.
Use Cases
- Mapping hydrothermal alteration zones based on the described Bleached, Iron, and Footwall zones
- Analyzing trace element anomalies for Fe, Mn, As, Sb, Hg, Co, Ba, and S concentrations
- Investigating spatial relationships between low-temperature veins and alteration intensity
- Assessing economic implications for fine-grained gold mineralization in altered alluvium
Strengths
- Dataset describes three distinct alteration zones with specific mineralogical characteristics
- Identifies eight trace elements (Fe, Mn, As, Sb, Hg, Co, Ba, S) with anomalously high concentrations
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
