Residual Total Magnetic Field Survey of the Marsh Lake Area, Yukon

Geo Data Solutions GDS Inc. conducted an aeromagnetic survey of the Marsh Lake area in Yukon, Canada, from January 12 to March 16, 2018. Data were collected using cesium vapour magnetometers mounted on a Beechcraft King Air and a Piper Navajo aircraft. The survey used a nominal traverse line spacing of 400 m, control line spacing of 2400 m, and a terrain clearance of 150 m.

Use Cases

• Map subsurface geological structures based on magnetic field anomalies.
• Support mineral exploration targeting by identifying magnetic signatures associated with ore deposits.
• Integrate with other geophysical data for regional geological interpretation.
• Calibrate airborne survey methodologies using the described flight parameters and instrumentation.

Strengths

• Survey conducted over a defined two-month period in early 2018.
• Specific technical parameters are provided, including line spacings of 400 m and 2400 m, and a flight altitude of 150 m.
• Data collection used split-beam cesium vapour magnetometers, which are standard for high-resolution aeromagnetic surveys.

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 surveyed area.
