First Vertical Derivative of the Magnetic Field, Wolf Lake Area Yukon Aeromagnetic Survey

An aeromagnetic survey of the Wolf Lake area in Yukon, Canada, covering parts of NTS 105B and 105C. The data were collected by Novatem Inc. between February 23 and April 2, 2019, using cesium vapour magnetometers mounted on aircraft. The survey employed a nominal traverse line spacing of 400 meters and a terrain clearance of 150 meters.

Use Cases

• Geological mapping based on magnetic field variations.
• Mineral exploration targeting based on magnetic anomalies.
• Geophysical modeling based on the first vertical derivative of the magnetic field.
• Regional geological structure analysis based on the survey's traverse and control line orientations.

Strengths

• Survey conducted with specific parameters: 400 m traverse line spacing and 2400 m control line spacing.
• Aircraft flew at a nominal terrain clearance of 150 m, providing high-resolution data.
• Data collection period is precisely documented from February 23 to April 2, 2019.

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 the specific survey area.
