Government of Yukon data describes placer gold deposits in the Indian River area, west-central Yukon. Deposits are grouped into five classes based on thickness, grain size, composition, age, process, landform, and exposure, with thicknesses ranging from 1.5 to 16 meters. The gravel deposits, from Pliocene(?) to Holocene age, are preserved as terraces and valley fills, with formation explained across lithofacies, element, reach, system, and sequence scales.
Use Cases
- Classifying placer deposits based on thickness, grain size, composition, age, process, landform, and exposure.
- Analyzing gold deposition sites based on bed roughness at the lithofacies scale.
- Mapping preferential gold enrichment in gravel bars at the element scale.
- Studying the influence of stream gradient on gold distribution at the reach scale.
- Identifying economic placer formation in the White Channel Gravel and Local Creek Gravel units at the sequence scale.
Strengths
- Deposit thickness is quantified, ranging from 1.5 to 16 meters.
- Deposits are systematically classified into five groups based on seven specific characteristics.
- Formation process is described across a hierarchy of five physical scales from meters to thousands of square kilometers.
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 open_canada.
