Aeromagnetic Survey of the Nash Creek Area, Yukon, 2020

Geo Data Solutions conducted an aeromagnetic survey of the Nash Creek area in Yukon from January 19 to March 28, 2020. The survey was flown at a nominal terrain clearance of 150 meters with traverse lines spaced 400 meters apart. It was funded by the Geo-Mapping for Energy and Minerals program (GEM-2) of Natural Resources Canada.

Use Cases

• Geological mapping based on residual total magnetic field maps.
• Mineral prospectivity analysis based on first vertical derivative magnetic field maps.
• Regional geophysical interpretation based on survey lines oriented N0°E with orthogonal control lines.

Strengths

• Survey conducted with a split-beam cesium vapour magnetometer mounted on a Beechcraft King Air aircraft.
• Includes 10 PDF maps: 5 residual total magnetic field maps and 5 first vertical derivative maps.
• Nominal flight parameters are specified, including 150 m terrain clearance and 400 m traverse line spacing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is delivered primarily as PDF maps, which may require processing for quantitative analysis.
