Aeromagnetic Survey First Vertical Derivative Map for Yukon's Eagle Plains

EON Geosciences Inc. collected this aeromagnetic data between April 10, 2009 and September 16, 2009 over Yukon's Eagle Plains region. The survey used cesium vapour magnetometers flown at a 250-meter terrain clearance, with data interpolated to a 200-meter grid. The International Geomagnetic Reference Field was not removed from the total magnetic field values.

Use Cases

• Identify geological structures and lithological contacts based on magnetic gradient patterns.
• Support mineral exploration targeting by mapping subsurface magnetic anomalies.
• Integrate with other geophysical datasets for regional geological interpretation.
• Assess magnetic field variations for geophysical research and modeling.

Strengths

• Data was collected using high-sensitivity cesium vapour magnetometers (0.005 nT).
• Flight lines were computer-analyzed and levelled to minimize intersection errors.
• Survey parameters are precisely documented, including 800 m traverse line spacing and 250 m nominal terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The International Geomagnetic Reference Field (IGRF) was not removed, which may affect certain analyses.
• Row count and exact file sizes are unknown, which may limit suitability assessment.
