Yukon placer deposits were surveyed in March 1993 using ground penetrating radar (GPR). The test covered 10 sites across different terrain types, measuring GPR penetration, overburden velocities, and resistivity. The data was collected by the Government of Yukon to evaluate GPR as a tool for bedrock mapping in mineral exploration.
Use Cases
- Evaluate GPR penetration depth based on terrain and material conditions described in the study
- Model bedrock reflection strength based on dielectric contrast between overburden and bedrock
- Compare GPR survey effectiveness in frozen versus thawed deposits as outlined in the description
Strengths
- Data from 10 distinct placer deposit sites provides comparative analysis
- Includes measurements of GPR penetration (10-28 m), overburden velocity, and resistivity
- Survey conditions are documented (frozen/thawed, glaciated/unglaciated)
Limitations
- Row count and column-level documentation are unknown, limiting suitability assessment
- Data is from a single month in 1993; temporal scope is narrow
- File formats are HTML and PDF, which may require extraction for analysis
